Psalm 110:1
The Lord said to my Lord,
“Sit at My right hand,
Till I make Your enemies Your footstool.”
Yeshua speaks of Psalm 110 as referring to the Messiah:
Yeshua said to them, “Why is it said that the Messiah is the son of David? David himself declares in the Book of Psalms: ‘The Lord said to my Lord: “Sit at my right hand until I make your enemies a footstool for your feet.”’ David calls him ‘Lord.’ How then can he be his son?”
~Luke 20:41-44
Yeshua makes it clear that it is He who sits at God’s right hand:
And Yeshua said, “I AM; and you shall see the Son of Man sitting at the right hand of Power, and coming with the clouds of heaven.”
~ Mark 14:62
God said to Moses, “I AM WHO I AM. This is what you are to say to the Israelites: ‘I AM has sent me to you.’
~ Exodus 3:14
