And the LORD discomfited Sisera, and all his chariots, and all his host, with the edge of the sword before Barak; so that Sisera lighted down off his chariot, and fled away on his feet. The Lord discomfited Sisera - ויהם יהוה vayiahom Jehovah; the Lord Confounded, threw them all into confusion, drove them pell-mell - caused chariots to break and overthrow chariots, and threw universal disorder into all their ranks. In this case Barak and his men had little to do but kill and pursue, and Sisera in order to escape, was obliged to abandon his chariot. There is no doubt all this was done by supernatural agency; God sent his angel and confounded them.
