Psalms 87:5

The Highest himself shall establish her— That is what David promised himself; that as he had built the city under the direction of God, and had fixed for the ark a proper habitation in it; so God would now establish it, by guarding it from its enemies, and providing for its future prosperity: and I think it appears from hence, that this and the foregoing verse are the Psalmist's own words, and not the words of God concerning Jerusalem, as Grotius, Le Clerc, and others, make them.
