2 Peter 2:20-22

Amplified Bible

²⁰ For if, after they have escaped the pollutions of the world by [personal] knowledge of our Lord and Savior Jesus Christ, they are again entangled in them and are overcome, their last condition has become worse for them than the first. ²¹ For it would have been better for them not to have [personally] known the way of righteousness, than to have known it and then to have turned back from the holy commandment [verbally] handed on to them. ²² The thing spoken of in the true proverb has happened to them, “The dog returns to his own vomit,” and, “A sow is washed only to wallow [again] in the mire.”^(A)
