Comentario sobre Salmos 132:13

For – It mentions Zion because it is called the city of David, since he rejoiced when it was revealed to him that the mountain of the House of the Lord is Zion.

For the Lord has chosen Zion – Because the choice of the seed of David was for the sake of the choice of Zion as I explained above. And it says that in the beginning the Lord chose Zion in the sense of a choice which excludes all other places, and afterwards ‘He desired it for His habitation,’ He desired the place in and of itself without looking at it in relation to rejecting anywhere else.
