8 Take a present to Elisha and ask him to ask God if I will get better.
9 So Hazael went to meet Elisha with forty camel loads of gifts from Damascus. When he found him, he said to him, “Benhadad sent me to ask you if he'd recover from his disease.”
10 Elisha said, “Tell him he will certainly recover – though the Lord told me he will die.”
11 Then Elisha began to cry. Hazael said, “Why are you crying?”
This seems to be the same Benhadad that King Ahab let escape back in Episode 143 - which upset God so much that he said he would kill Ahab for it. (1 Kings 20: 31-42)
And Hazael became king of Syria. (8:15)
In Episode 142 (1 Kings 19:15), God told Elijah to anoint Hazel as king of Syria. Elijah never did as God commanded. But now, long after Elijah has died and Elisha has replaced him a prophet, Hazael becomes king of Syria after murdering King Benhadad. It was all part of God's plan. (It was just delayed a bit.)
