Some time has passed and Jesus is now in the temple. This is not part of the previous conversation. AT: "Later, while Jesus was teaching in the temple area, he said to the people" (See: [[rc://en/ta/man/translate/figs-explicit]])
Jesus uses this question to get the people to think deeply about the Psalm he is about to quote. This can be written as a statement. AT: "Consider why the scribes say the Christ is the son of David." (See: [[rc://en/ta/man/translate/figs-rquestion]])
This word "himself" refers to David and is used to place emphasis on him and what he said. AT: "It was David who" (See: [[rc://en/ta/man/translate/figs-rpronouns]])
# in the Holy Spirit
This means that he was inspired by the Holy Spirit, that is, the Holy Spirit directed David in what he said. AT: "inspired by the Holy Spirit" (See: [[rc://en/ta/man/translate/figs-idiom]])
# said, 'The Lord said to my Lord
Here David calls God "The Lord" and calls the Christ "my Lord." This can be written more clearly. AT: "said about the Christ, 'The Lord God said to my Lord" (See: [[rc://en/ta/man/translate/figs-explicit]])
# sit at my right hand, until I make your enemies your footstool

# until I make your enemies your footstool
In this quote, God speaks of defeating enemies as making them into a footstool. AT: "until I completely defeat your enemies" (See: [[rc://en/ta/man/translate/figs-metaphor]])
