Psalms 110:1
A Psalm of David.
The LORD, (הוהי Yahweh – “the existing One” = God the Father) said unto my Lord (ןודא adown – “lord, master” pointing to Jesus), Sit thou at my right hand, until I make thine enemies (personal and national) thy footstool.
As this verse caused for some questions I thought to help you explaining the two times Lord.
