I can’t speak for User46952. I’d like to hear his response to your question.
While we wait: I believe the God and Father of Jesus is the God of Abraham, Isaac and Jacob - Almighty God.
Blessed be the God and Father of our Lord Jesus Christ.
OT Jehovah is Jesus pre-incarnation:
Zech 12:8-10 Identifies Jehovah with Jesus Christ
8) The LORD (Jehovah) defend the inhabitants of Jerusalem; & he that is feeble among them at that day shall be as David; & the house of David shall be as God, as the angel of the LORD before them
9) it shall come to pass in that day, "I" will seek to destroy all the nations that come against Jerusalem
10) I will pour upon the house of David, & upon the inhabitants of Jerusalem, the spirit of grace & of supplications & they shall look upon me whom they have pierced, & they shall mourn for him, as one mourneth for his only son, & shall be in bitterness for him, as one that is in bitterness for his first born
In verse 8 the LORD, (Jehovah), is speaking. In verses 9 & 10 the pronoun, "I", refers to the same LORD, or Jehovah "I" will seek to destroy & "I" will pout out upon the house of David
"""Here's the real key"""
Vs 10 they shall look upon me (Jehovah) whom they pierced & they shall mourn for him, as one mourneth for his only son, & shall be in bitterness for him, as one that is in bitterness for his first born
Clearly, Jehovah is stating He vis the One that shall be pierced & mourned for.
Jesus is the pre-incarnation OT Jehovah:
1 In the beginning was the Word, and the Word was with God, and the Word was God.
(NOTE: Jesus is the Word Rev 19:13)
3 All things were made by him; and without him was not any thing made that was made.
(NOTE: The Word/Jesus that was with & was God created all things)
10 He was in the world, and the world was made by him, and the world knew him not.
(NOTE: The Word/Jesus that was with & was God created the world)
14 (A) And the Word was made flesh, and dwelt among us,
(NOTE: The pre-existing Word/Jesus became flesh)
Jn 8:58 Jesus said unto them, Verily, verily, I say unto you, Before Abraham was, I am.
(NOTE: See Ex 3:14)
