Trinity: Oneness in unity not in number: Yachid vs. Echad

"Hear, O Israel! Yahweh is our God, Yahweh is one [Echad]!" Deuteronomy 6:4

Yachid vs. Echad: The most important verse Jews memorized in the Bible was Deut 6:4: "Hear, O Israel! Yahweh is our God, Yahweh is one [Echad]!" There are a few words in Hebrew that the Holy Spirit could have used a word the has one exclusive meaning: the numeric, solitary oneness of God ("yachid" or "bad").

Instead the Holy Spirit chose to use the Hebrew word, "echad" which is used most often as a unified one, and sometimes as numeric oneness. For example, when God said in Genesis 2:24 "the two shall become one [echad] flesh" it is the same word for "one" that was used in Deut 6:4.

This is most troubling for Jews and Anti-Trinitarians since the word yachid, the main Hebrew word for solitary oneness, is never used in reference to God.




  1. Christians, being the excellent scholars of ancient Biblical Hebrew openly admit that Echad is used many times in the Old Testament to mean one and one alone: "Two are better than one [Echad] because they have a good return for their labor. For if either of them falls, the one [Echad] will lift up his companion. But woe to the one [Echad] who falls when there is not another to lift him up. Furthermore, if two lie down together they keep warm, but how can one [Echad] be warm alone? And if one [Echad] can overpower him who is alone, two can resist him. A cord of three strands is not quickly torn apart." (Ecclesiastes 4:9–12)
    1. The argument that not that ECHAD is Deut 6:4. The argument is that this word has two meanings: unified and singular one.
    2. The argument is that the word YACHID, which always means one and ONE ALONE (not a unified one) is NEVER used of God ANYWHERE in the Old Testament.
    3. The Hebrew word "HEN" means one and only one and is used of God: "“Now, O Lord our God, deliver us from his hand that all the kingdoms of the earth may know that You alone [HEN], Lord, are God.”" (Isaiah 37:20) But never in the Torah.
    4. This fact indeed deeply troubles Jews today.
  2. The debate over the implications of the various usage's of two Hebrew words [Yachid vs. Echad] translated "one" is as intriguing as it is complex.
    1. The etymology of the Hebrew word yachid (one) is derived from echad in the same way that the English word "only" is derived from the word "one". That yachid is from the same root family of words as echad is seen from the similarity of spelling. So "yachid" is to "only", what "echad" is to "one".
    2. About the only fact that all on both sides of the debate agree on, is that yachid indisputably means an absolute numeric one and is never used to describe God. Jews and Anti-Trinitarians would naturally expect such a word to be commonly used of God. Having said this, when we cross over to the Greek, in parallel passages that use "yachid", we find a correspondence with the Greek word "mono". We do find "mono" used of God in the New Testament describing his oneness. So while yachid is never used of God's oneness in the Old Testament, the corresponding word "mono" is used of God's oneness in the New Testament. But this is exactly what Trinitarians would expect to be the case because there are three persons in the one God.
    3. Hebrew is a very simple language, but Greek is quite complex and specific. Some Trinitarians overemphasize the clear differences between "yachid and echad" in the Hebrew. Yes, "echad" is a unified one, but it is also used of a numeric one as well. Yes, "yachid" is never used in reference to God's oneness, but the word "bad" is used and it is synonymous with numeric oneness to yachid. When we cross over to the Greek, we find a similar blur in the words used of God that mean unified versus numeric oneness. If the Holy Spirit intended to convey Trinity hidden in the Old Testament in the words "yachid and echad", we would expect such a distinction to be even more pronounced in the Greek, since it is a more specific language than Hebrew. But we find exactly the same in the New Testament as we do in the old, namely a combination of words meaning unified versus numeric oneness being employed to describe God's oneness.
  3. Having said all this, perhaps the Holy Spirit did want us to look back at the Old Testament and perceive the differences between "yachid and echad". Add to this plural pronouns like: "let US make man in OUR image" and Trinitarians have irrefutable evidence of the trinity in the Old Testament.
    1. Trinitarians can be confident that the word "echad" used to describe God's oneness, is exactly what we would expect to find. Jews, anti-Trinitarians and Unitarians are nervous about the fact that the most direct and important statements in the Old Testament about God's oneness (Deut 6:4) use the unified one [echad] instead of a words that always mean numeric oneness like "yachid" and "bad".
    2. There isn't a single Jew or anti-Trinitarian today who, given the chance, would not go back in time and tell Moses his choice of ECHAD instead of YACHID in Deut 6:4 will cause them grief in the future.
    3. As we will see, Jews did change words and start using the word YACHID in reference to God after they rejected conversion to Christianity.
  4. Jesus quoted Deut 6:4 in Mk 12:29 and chose the "unified oneness" word "hen" which is the same word used by Jesus in Mt 19:5, "the two shall become one (hen) flesh.
    1. It is significant that Jesus did not use "mono" in Mk 12:29. The word "hen" directly corresponds to "echad" which was used in Deut 6:4.
    2. Both texts used "unified oneness" words rather than absolute numeric oneness to the exclusion of all others.
    3. This is a very devastating pattern of using the unified one as opposed to the singular one in both the Old and New Testaments in Deut 6:4.

 A. Jews, after the rise of Christianity, were compelled to change the Hebrew word for "one" from echad to yachid:

  1. For any Jew to use "Yachid" to refer to the oneness of God is UNBIBLICAL because the Holy Spirit never willed that any scripture in the Bible uses the word YACHID in reference to God.
  2. It is claimed by Jews who attack Christian theology that the use of the word ECHAD in Deut 6:4 causes them no problem since the word ECHAD is used in other places in the Old Testament to refer to a clearly single person. But this ignores the powerful argument made by Christians, namely that the word YACHID, which always means one and only one, is never used of God.
  3. If the use of "echad" instead of "yachid" in Deut 6:4 gave no help to the early Christians in proving to the Jews that Yahweh of the Old Testament was the multi-personal God of the Christians (Father, Son, Holy Spirit) then Jews would not have felt compelled replace the word in their dogmas and statements of faith. If it is really that insignificant, then they would have told us the argument Christians were using to prove trinity is invalid to native Hebrews who know and speak the language.
  4. A man named Moses Maimonides who lived in the 12th century AD, was Jewish Rabbi and philosopher who compiled a creed in Hebrew using the Aramaic alphabet with 13 articles. While he did use the word echad in Deut 6:4, in his 13 point creed, he uses the UNBIBLICAL word yachid instead of echad:
    Hebrew using Aramaic alphabet: אֲנִי מַאֲמִין בֶּאֱמוּנָה שְׁלֵמָה, שֶׁהַבּורֵא יִתְבָּרַךְ שְׁמו הוּא יָחִיד וְאֵין יְחִידוּת כָּמוהוּ בְּשׁוּם פָּנִים, וְהוּא לְבַדּו אֱלהֵינוּ, הָיָה הוֶה וְיִהְיֶה
    1. Translation 1: "I believe with a perfect faith that the Creator, blessed be His name, is an absolute one [yachid]".
    2. Translation 2: “I believe with perfect faith that the Creator, blessed be his name is one and there is no unity like his in any way. He alone is our G-d- He was, he is, and he will be.”
  5. Modern Jewish prayer books use the UNBIBLICAL word "yachid" to describe God.
    1. Remember, by UNBIBLICAL, we do not mean that Yachid is not used in the Bible.
    2. By UNBIBLICAL we mean that YACHID is never used to describe God's oneness in the Torah or anywhere in the entire Old Testament.
  6. Elohim vs. El
    1. Elohim is plural "gods". El is singular "god".
    2. The God of the bible (YHWH) is referred to in the plural Elohim thousands of times.
    3. "Actually, the fact that God is called ʾelohim (translated as “God” when referring to the Lord and as either “god” or “gods” when referring to idols) is not unusual. In the Ancient Near East, it was common to refer to the deity in the compound plural, and when speaking of an owner or master, it was often the rule to speak of him in such terms. To give you just a few examples, Abraham’s servant speaks of his master in the plural in Genesis 24 (ʾadonim, literally, “lords”), Joseph speaks of his master Potiphar in the plural in Genesis 39, and David the king is spoken of as “lords” in 1 Kings 1:11. In Exodus 21, to translate literally and incorrectly, the law speaks of a slave and his masters (ʾadonim, referring to just one master), in Isaiah 19:4, the prophet tells Israel that God will hand them over to a cruel lord (Hebrew, ʾadonim qasheh, a plural noun with a singular adjective), and Isaiah 1:3 tells us that a donkey knows the feeding crib of its masters (baʾalim, referring to just one person; cf. the first half of the verse in which reference is made to an ox’s owner—in the singular). These examples, which are really very common, show clearly that compound plurals were often used to speak of leaders, owners, masters, or kings. How much more then could similar expressions be used to speak of the Lord, the Master, the King, and the God." (Answering Jewish objections to Jesus: Theological objections, Michael L. Brow, A Jew who converted to Christianity, Vol. 2, p9, 2000 AD)
    4. This correct observation does not change the fact that the Holy Spirit chose to use a plural word to refer to God in a polytheistic world of pagan gods instead of the singular "el".
  7. It must be most troubling for Jews that their word of choice (yachid) to describe God's oneness is never actually used in the Bible. They should give up their 2000 year old rebellion against Christianity, be more truthful and not engage in a deliberate action of misrepresenting what the Bible says. Then they could use Bible words to describe the one true God and creep closer to becoming Christians!

B. Five different words for "one" in the Bible:





unified one: Gen. 2:24; Deut. 6:4
absolute numeric one: Ezekiel 33:24

Used of God's oneness


Always absolute numeric one: Judges 11:34

Never used of God's oneness


Absolute numeric one: Isaiah 37:20

Used of God's oneness


Unified one: John 10:30; Matthew 19:5; Mk 12:29
absolute numeric one: Galatians 3:20

Used of God's oneness


absolute numeric one: Matthew 24:36; 1 Timothy 1:17

Used of God's oneness

C. "Echad", denoting a unified one in the OT is translated only "hen" in the NT:

Here are a number of Old Testament passages that are either directly quoted in the New Testament, or contain parallel thoughts.

D. "Echad", denoting an absolute and numeric oneness in the OT is translated both "hen" and "monos" in the NT:

Echad is used to designate a single individual or thing, numerical oneness. In these texts we consider Echad to be synonymous with yachid. Yet we find the parallel passages of thought in the New Testament are translated from two different Greek words: "hen" and "monos". Like "echad", "hen" is used in two different ways: unified one and numeric one. "Monos", however, always means a numeric one. This means we do not find a consistent pattern between the Hebrew and Greek languages.

  1. When speaking of God's oneness, what we see is a mix of words, both in the Hebrew and the Greek. There does not appear to be a clear pattern of usage: In the Old Testament, "echad" is used both as a unified one and numeric oneness and "bad" is also used which means a numeric oneness. Similarly, in the New Testament, "hen" is used both as a unified one and numeric oneness and "monos" is also used which means a numeric oneness.
  2. These facts delight Trinitarians and send Anti-Trinitarians and Unitarians alike scurrying for the shadows. While Trinitarians would expect both kinds of words to be used in reference to God, Anti-Trinitarian are left with their mouths hanging open in bewilderment. To make matters even worse, the word "monos" is not only used of God's oneness (John 5:44; 17:3), but also Jesus is said to be the "monos Master", "monos Lord" and "monos Sovereign" (1 Timothy 6:16; Jude 4). This proves that Jn 17:3 no more excludes Jesus from being "true God" than 1 Timothy 6:16 and Jude 4 exclude the Father from being Master, Lord and Sovereign. (The official interpretation of 1 Timothy 6:16 the Jehovah's Witnesses and the Watchtower is that 1 Timothy 6:16 is speaking solely of Christ.) Click here for a detailed look at this powerful argument in John 17:3.
  3. Anti-Trinitarians who reject the fact that "echad" means a unified one between individuals, should always remember that shortly after the rise of Christianity, the Jews replaced "echad" with "yachid" in Deut 6:4. Obviously these Jews who knew the Hebrew language 2000 years ago, saw something modern Unitarians do not.
  4. So in the end it is a win-win for Trinitarians! It is most devastating to Jews and Anti-Trinitarians that Deut 6:4 uses "echad", the word for a unified one between individuals. The same word echad is used to say that God is one and that husband and wife are one. This laid the ground work for the Trinity to be revealed in Christ and his apostles who could look back to the most important Jewish Bible verse and show them Jesus was there too! Instead of converting to Christianity, the Jews twisted the word of God and started telling lies about the resurrection of Jesus.
  5. Zechariah prophesied that at the time of the Messiah all will know that God is one: "And the Lord will be king over all the earth; in that day the Lord will be the only one [echad], and His name the only one [echad]." (Zechariah 14:9)
    1. Again the unified word for one is used!
    2. If ever there was a place YACHID would have been used, this would have been it, but no, the unified one was used.
  6. Today Jews live under a veil of darkness unable to come to the truth:
    1. "But their minds were hardened; for until this very day at the reading of the old covenant the same veil remains unlifted, because it is removed in Christ. But to this day whenever Moses is read, a veil lies over their heart; but whenever a person turns to the Lord, the veil is taken away." (2 Corinthians 3:14–16)
