Does the Old Testament say that God has a Son? The Tenakh is what Christians call the Old Testament. The Tenakh is the sacred writings inspired by God for Jews and Gentiles (Non-Jews). The Jewish people have been faithful in their responsibility to keep these holy writings free from error. So, what does the Tenakh say about God having a Son?
6“I have installed my king on Zion, my holy mountain.” 7I will proclaim the LORD’s decree: He said to me, “You are my son; today I have become your father. 8Ask me, and I will make the nations your inheritance, the ends of the earth your possession. 9You will break them with a rod of iron; you will dash them to pieces like pottery.” 10Therefore, you kings, be wise; be warned, you rulers of the earth. 11Serve the LORD with fear and celebrate his rule with trembling. 12Kiss his son, or he will be angry and your way will lead to your destruction, for his wrath can flare up in a moment. Blessed are all who take refuge in him (Psalm 2:6-12).
A King is coming to the people of Earth, a mighty warrior King who will put down all evil and rebellion against the Most High God. Verse 12 says that we are to pay homage (kiss) to this King. Everyone who places their trust in this King will be blessed and be able to take refuge in Him (v. 12). The Old Testament, the Tenakh, says that this King will be God Himself.
Behold, the Lord GOD will come with strong hand, and his arm shall rule for him: behold, his reward is with him, and his work before him (Isaiah 40:10).
You may be a Jewish person but perhaps have never read the Tenakh, what Christians call the Old Testament, for most Jewish people only read the first five books of Moses. There are other places where the Scriptures talk about the Son of God, for instance, in the book of the Proverbs, again in the Tenakh. When talking about some of the attributes of the Creator God, the inspired writer says,
Who has gone up to heaven and come down? Whose hands have gathered up the wind? Who has wrapped up the waters in a cloak? Who has established all the ends of the earth? What is his name, and what is the name of his son? Surely you know! (Proverbs 30:4).
This mighty King of Israel is Jesus, whose name means The Lord Saves. He has come once before to deliver us from the guilt and shame of our sin, but He is coming again as our mighty King to deliver us from the satanic forces of deception at work in this world. Indeed there is never a better time than today to kiss the Son and take refuge in Him. Bow the knee to Him and call upon His Name, and Christ will forgive your sin and wash away your guilt.
