'Deceiving' in the Bible

"And the LORD asked him, "How?' ""I will go,' he announced, "and I will be a deceiving spirit in the mouth of all of his prophets!' "So the LORD said, "You're just the one to deceive him. You will be successful. Go and do it.'

Now therefore, behold, the Lord has put a deceiving spirit in the mouth of all these your prophets; and the Lord has proclaimed disaster against you.”
