The prophet Elisha summoned a man from the company of the prophets and said to him, "Tuck your cloak into your belt, take this flask of oil with you and go to Ramoth Gilead. When you get there, look for Jehu son of Jehoshaphat, the son of Nimshi. Go to him, get him away from his companions and take him into an inner room. Then take the flask and pour the oil on his head and declare, 'This is what the LORD says: I anoint you king over Israel.' Then open the door and run; don't delay!"
So he did it.
When Jehu went out to his fellow officers, one of them asked him, "Is everything all right? Why did this madman come to you?" "You know the man and the sort of things he says," Jehu replied.
"That's not true!" they said. "Tell us." Jehu said, "Here is what he told me: 'This is what the LORD says: I anoint you king over Israel.' "
They hurried and took their cloaks and spread them under him on the bare steps. Then they blew the trumpet and shouted, "Jehu is king!"
Isn't it strange how they called the prophet a madman, then they gladly took Jehu and made him king, believeing that becuz a prophet of the LORD said it, than it would be true. and something itresting I also found is that "Bad company corrupts good character." As you know. And apparently this guy wasn't with any "corrupt characters" and he was a good king!
