The Bible is Completely True

God sent a lying spirit to be in the mouth of all Ahab's prophets, and Elijah affirmed that they had a lying spirit. It's the same thing that happened to Judas. Jesus said it would've been better if he weren't born. Jesus prophesied that one of his disciples would betray him and it happened, the devil entered into Judas. The same thing with Peter. Jesus rebuked the devil that got into Peter. These are two other instances other than what we see in 1 Kings where the devil got into people. 1 Kings just shows us that nothing happens without God's approval. There are no mistakes in the Bible, the Bible is 100% truth.
