And the LORD smote the king, so that he was a leper unto the day of his death. 15:5
Trivia: In 2 Kings 17, what did God do to the foreiners who didn't fear or know him well enough?
Seems suspicious, doesn't it? Especially when you consider how much God hated Benhadad. God killed Ahab and his family for not killing Benhadad. Maybe Hazael did the job for God when he smothered him. 8:7-15
