This Psalm was composed upon the occasion of some eminent deliverance vouchsafed by God to the city of Jerusalem from some potent enemy and dreadful danger; either that in Jehoshaphat’s time, 2Ch 20$, or that under Hezekiah, 2Ki 18$, 19$; in both which times there were holy prophets, by some of whom this Psalm might be made.
A Song and Psalm; of which see See Poole "Psa_30:1", which hath the same title.
The prophet describeth the glory and excellency of the church, Psa_48:1-3, preserved from her potent enemies, Psa_48:4-8 for which God is glorified, Psa_48:9,10, and the faithful invited to take notice of its beauty and firmness, to transmit it to following generations, Psa_48:11-14.
In the city of our God; in Jerusalem, which he hath chosen for his dwelling-place.
In the mountain of his holiness, i.e. in his holy mountain; either Zion, where the ark and tabernacle was; or rather Moriah, where the temple now was. Although both of them are supposed by some to be but one mountain, having two tops; and it is certain that both are frequently called by one name, to wit, Zion.
