Is the Trinity in the Old Testament — Meaning Explained

The Old Testament plants seeds of the Trinity doctrine that blossom in the New. Genesis 1:26 records God saying, 'Let us make man in our image' — a plural self-reference. Genesis 11:7 repeats: 'Let us go down.' The Hebrew word for God, Elohim, is grammatically plural with a singular verb, suggesting plurality within unity. The Spirit of God appears in Genesis 1:2, 'moved upon the face of the waters.' Isaiah 48:16 contains a remarkable statement: 'The Lord GOD, and his Spirit, hath sent me' — three persons in one verse. The Angel of the LORD (Genesis 16:7-13, Exodus 3:2-6) receives worship and is identified as God — many scholars see this as the pre-incarnate Christ. Isaiah 63:9-10 mentions the LORD, the angel of His presence, and His Holy Spirit together. The Shema — 'The LORD our God is one LORD' (Deuteronomy 6:4) — uses echad, which can denote compound unity (as in 'one flesh,' Genesis 2:24), not yachid (absolute singularity).
