The Lord said to my Lord

This is a quotation from the book of Psalms which says "Yahweh said to my Lord." But the Jews stopped saying "Yahweh" and often said "Lord" instead. AT: "The Lord God said to my Lord" or "God said to my Lord"

my Lord

David was referring to the Christ as "my Lord."

Sit at my right hand

To sit at the "right hand of God" is a symbolic action of receiving great honor and authority from God. AT: "Sit in the place of honor beside me" (See: rc://en/ta/man/translate/translate-symaction)
