Here Yahweh is saying that these people (Israel) are his witnesses and his servant. The intention? That they may know him and believe in him. Nowhere here does it say that Yahweh is a suffering servant. How can Yahweh be a servant when he is the supreme and almighty? He cannot and will not be subject to anyone!
Reread it again.
Ye are my witnesses, saith Yahweh, and my servant whom I have chosen: that ye may know and believe me, and understand that I am he: before me there was no Elohim formed, neither shall there be after me.
YHVH says that the servant is him,
I am He
I stated elsewhere we believe in the 66 books of the Bible so yes, we do study the Old Testament.
Then why do you deny that Hashem came in flesh?
I dont understand what you mean here. A couple of months studying what aspect of the Old Testament?
Ha' Nevarim (Prophets).
I dont understand what you mean here either. How are we confused about what the Tanakh teaches
You deny that Hashem is the Messiah, i.e that Jesus is God-incarnate, and your sect denies this meanwhile claiming to be Sola Scriptura.
I just want to know on what basis you guys deny Messiah is not YHVH? So please explain this to me.
