2 Peter 2:17-19

Those false teachers are like springs without water and clouds blown by a storm. A place in the blackest darkness has been kept for them. They brag with words that mean nothing. By their evil desires they lead people into the trap of sin—people who are just beginning to escape from others who live in error. They promise them freedom, but they themselves are not free. They are slaves of things that will be destroyed. For people are slaves of anything that controls them.
