(3.) The king and kingdom shall be put into the utmost confusion and consternation by the enemies' invading them, v. 41-43. All the expressions here used to denote the formidable power of the invaders, the terrors wherewith they should array themselves, and the great fright which both court and country should be put into thereby, we met with before (ch. vi. 22-24) concerning the Chaldeans' invading the land of Judah. The battle which is there said to be against thee, O daughter of Zion! is here said to be against thee, O daughter of Babylon! to intimate that they should be paid in their own coin. God can find out such as shall be for terror and destruction to those that are for terror and destruction to others; and those who have dealt cruelly, and have shown no mercy, may expect to be cruelly dealt with, and to find no mercy. Only there is one difference between these passages; there it is said, We have heard the fame thereof and our hands wax feeble; here it is said, The king of Babylon has heard the report and his hands waxed feeble, which intimates that that proud and daring prince shall, in the day of his distress, be as weak and dispirited as the meanest Israelites were in the day of their distress.
