During the reign of Jeroboam, God sent a prophet to deliver a message to the king. After ignoring the prophecy, the king invited the prophet to his home for a meal. But the prophet refused Jeroboam’s offer, because God had told him not to eat or drink until he got back to his own home.
On the way home, the prophet met an old prophet. The old prophet also invited him to have a meal, and the younger prophet explained again that he had to wait till he got home to eat. But the old prophet lied and told him that God wanted him to eat and drink with him. So the younger prophet went to the old prophet’s house and ate and drank. Then the old prophet declared that the younger prophet had disobeyed God and would be punished. The younger prophet tried to go home, but God sent a lion after him, and it killed him.
The end.
The moral of the story
Don’t listen to prophets who claim to be telling you what God wants you to do. They might be lying.
(Of course, when you get conflicting instructions from God, you risk getting punished regardless of whether you go with the first thing God told you or the last thing God told you.)
