King Ahab is condemned by a prophet (not Elijah) for making a treaty with a king he was supposed to let go. It’s quite a convoluted tale, hard to follow.
It’s confusing that there are prophets everywhere, schools of prophets, but in the last chapter Elijah felt so alone, that he was the last prophet left.
It’s also interesting seeing God use as corrupt a king as Ahab to have victories in his name.
Anyway, its setting up the fall of Ahab.
