# whom you choose ... your courts

The words "you" and "your" in this verse refer to Yahweh.

# live in your courts

"worship often in your courts" 

# We will be satisfied with the goodness of your house, your holy temple

"The goodness of your house, your holy temple, will satisfy us"

# We will be

Here the word "we" refers to David and the people of Israel, but not to God, to whom he is speaking.
