Habakkuk 1:10

The kings and rulers of the lands they overran were no threat to them. They laughed at them and their fortified cities in contempt (cf. 2 Kings 25:7). They heaped up rubble to conquer fortifications; they did not need special machines but used whatever they found to build siege ramps to conquer them (cf. 2 Samuel 20:15; 2 Kings 19:32; Ezekiel 4:2; Ezekiel 21:22; Ezekiel 26:8-9).
