Known - By long experience. Palaces - Possibly he may point at the king's palace and the temple, which was the palace of the king of heaven; which two palaces God did in a singular manner protect, and by protecting them, protected the whole city and people.
The kings - Either those kings confederate against Jehoshaphat, Ch2 20:1, or the Assyrian princes; whom they vain - gloriously called kings, Isa 10:8. Passed - In their march towards Jerusalem.
Saw it - They did only look upon it, but not come into it, nor shoot an arrow there - nor cast a bank against it, Kg2 19:32. Marvelled - At the wonderful works wrought by God.
Breakest - Thou didst no less violently and suddenly destroy these raging enemies of Jerusalem, than sometimes thou destroyest the ships at sea with a fierce and vehement wind, such as the eastern winds were in those parts.
Heard - The predictions of the prophets have been verified by the events. Establish - God will defend her in all succeeding ages. And so God would have done, if Jerusalem had not forsaken him, and forfeited his protection.
So - Thou art acknowledged to be such an one as thou hast affirmed thyself to be in thy Word, God Almighty, or All - sufficient, the Lord of hosts, and a strong tower to all that trust in thee. Righteousness - Of righteous actions; by which thou discoverest thy holiness.
Tell - He bids them mark well her towers, bulwarks, and palaces, with thankfulness to God, when they should find upon enquiry, that not one of them were demolished.
