¹⁷ Those false teachers are like rivers that have no water. They are like clouds blown by a storm. A place in the blackest darkness has been kept for them. ¹⁸ They brag with words that mean nothing. By their evil desires they lead people into the trap of sin. They lead away people who are just beginning to escape from other people who live in error. ¹⁹ They promise them freedom, but they themselves are not free. They are slaves of things that will be destroyed. For a person is a slave of anything that controls him.
