What the heck is so hard to get?
Elohim can mean more than the one Almighty God, the Son is Elohim like the other sons of God, read psalm 82.
It is like in English when you say the Administration. Well there is only one CEO Almighty. Not all members of an administration are the same person, but all are administrating, and running things. Not all members of the Board are the one same person, but all are members of the one same Board.
The OT is henotheistic not monotheistic. There are many Elohim, but no Elohim is the Father except the Father, the only one who comes close is the Son, the spokesman for the Father. They can both wield their administrative power through the Spirit. The Board is a Divine Council.
Search for Michael Heiser and the Divine Council for some good insight into what the Hebrew text says about Elohim.
