1 Kings 20:31 (KJV)

And they pitched one over against the other seven days. And so it was, that in the seventh day the battle was joined: and the children of Israel slew of the Syrians an hundred thousand footmen in one day.

But the rest fled to Aphek, into the city; and there a wall fell upon twenty and seven thousand of the men that were left. And Ben–hadad fled, and came into the city, into an inner chamber.

And his servants said unto him, Behold now, we have heard that the kings of the house of Israel are merciful kings: let us, I pray thee, put sackcloth on our loins, and ropes upon our heads, and go out to the king of Israel: peradventure he will save thy life.

So they girded sackcloth on their loins, and put ropes on their heads, and came to the king of Israel, and said, Thy servant Ben–hadad saith, I pray thee, let me live. And he said, Is he yet alive? he is my brother.

Now the men did diligently observe whether any thing would come from him, and did hastily catch it: and they said, Thy brother Ben–hadad. Then he said, Go ye, bring him. Then Ben–hadad came forth to him; and he caused him to come up into the chariot.
