1 Kings 20:31-33

31Ben-hadad’s officers said to him, “Sir, we have heard that the kings of Israel are merciful. So let’s humble ourselves by wearing burlap around our waists and putting ropes on our heads, and surrender to the king of Israel. Then perhaps he will let you live.”

32So they put on burlap and ropes, and they went to the king of Israel and begged, “Your servant Ben-hadad says, ‘Please let me live!’” The king of Israel responded, “Is he still alive? He is my brother!”

33The men took this as a good sign and quickly picked up on his words. “Yes,” they said, “your brother Ben-hadad!” “Go and get him,” the king of Israel told them. And when Ben-hadad arrived, Ahab invited him up into his chariot.
