John Trapp on Nahum 2:6

Verſe 6. The gates of the rivers ſhall be opened] Notwithſtanding all fore-mentioned indeavours to ſave the city, the water-gates or thoſe that ſtood neare the river Tigris, flew open either by meanes of that inundation above-mentioned, or by the enemies irruption; or the trechery of ſome that were within.

and the pallace ſhall be diſſolved] Or melted, haply by that inundation: howſoever, by hoſtile impreſſion: whether we underſtand it of the Palace Royall, or the Idol-temple or both(the word will beare either) for it was not unuſual for Princes to have their houſes neare to the temples, as the kings of Judah had Ier. 22.14. The Trojans had their Palladium in the Tower: the Romans their Temple of Jupiter Capitolinus in the Capitoll: Conſtantine the great, built the Lateran Church in his Laterane palace; William Rufus, his Weſtminſter-hall, neare the Minſter.
