Verse 21. - And the king of Israel went out [It looks as if Ahab had remained within the city until the defeat of the Syrians was assured], and smote [LXX. καὶ ἐλαβε, and captured] the horses and chariots [i.e., the cavalry and chariotry; cf. ver. 1], and slew the Syrians with a great slaughter. [Heb. in Syria a great, etc.]

20:12-21 The proud Syrians were beaten, and the despised Israelites were conquerors. The orders of the proud, drunken king disordered his troops, and prevented them from attacking the Israelites. Those that are most secure, are commonly least courageous. Ahab slew the Syrians with a great slaughter. God often makes one wicked man a scourge to another.And the king of Israel went out,.... Of Samaria; when he saw the Syrians fleeing, and his army pursuing, he went forth, perhaps, with more forces, who were now willing to join with him; Josephus (c) says, Ahab had another army within the walls:

and smote the horses and chariots; that is, the men that rode on horses; and in chariots, the Syrian cavalry:

and slew the Syrians with a great slaughter; how many were slain is not said; but the Jewish historian (d) says they plundered the camp, in which were much riches, and great plenty of gold and silver, and took their chariots and horses, and returned to the city of Samaria.
