'Lying' in the Bible
The old prophet then said, "I too am a prophet like you. An angel told me with the Lord's authority, 'Bring him back with you to your house so he can eat and drink.'" But he was lying to him.
As the prophet from Judah was traveling, a lion attacked him on the road and killed him. His corpse was lying on the road, and the donkey and the lion just stood there beside it.
Some men came by and saw the corpse lying in the road with the lion standing beside it. They went and reported what they had seen in the city where the old prophet lived.
He went and found the corpse lying in the road with the donkey and the lion standing beside it; the lion had neither eaten the corpse nor attacked the donkey.
He replied, 'I will go out and be a lying spirit in the mouths of all his prophets.' The Lord said, 'Deceive and overpower him. Go out and do as you have proposed.'
So now, look, the Lord has placed a lying spirit in the mouths of all these prophets of yours; but the Lord has decreed disaster for you."
