II. The entrance that was opened to them into the city by the sudden fall of the walls, or at least that part of the wall over against which they then were when they gave the shout (v. 20): The wall fell down flat, and probably killed abundance of people, the guards that stood sentinel upon it, or others that crowded about it, to look at the Israelites that were walking round. We read of thousands killed by the fall of a wall, 1 Kings xx. 30. That which they trusted to for defence proved their destruction. The sudden fall of the wall, no doubt, put the inhabitants into such a consternation that they had no strength nor spirit to make any resistance, but they became an easy prey to the sword of Israel, and saw to how little purpose it was to shut their gates against a people that had the Lord on the head of them, Mic. ii. 13. Note, The God of heaven easily can, and certainly will, break down all the opposing power of his and his church's enemies. Gates of brass and bars of iron are, before him, but as straw and rotten wood, Isa. xlv. 1, 2. Who will bring me into the strong city? Wilt not thou, O God? Ps. lx. 9, 10. Thus shall Satan's kingdom fall, nor shall any prosper that harden themselves against God.
