Kings III 21:19 In-Context

17 And the young men the heads of the districts went forth first; and they send and report to the king of Syria, saying, There are men come forth out of Samaria.
18 And he said to them, If they come forth peaceably, take them alive; and if they come forth to war, take them alive:
19 and let not the young men the heads of the districts go forth of the city. And the force that was behind them
20 smote each one the man next to him; and each one a second time smote the man next to him: and Syria fled, and Israel pursued them; and the son of Ader, the king of Syria, escapes on the horse of a horseman.
21 And the king of Israel went forth, and took all the horses and the chariots, and smote with a great slaughter in Syria.
