Ezekiel 18:24 KJV‬
[24] But when the righteous turneth away from his righteousness, and committeth iniquity, and doeth according to all the abominations that the wicked man doeth, shall he live? All his righteousness that he hath done shall not be mentioned: in his trespass that he hath trespassed, and in his sin that he hath sinned, in them shall he die.

‭Proverbs 26:11-12 KJV‬
[11] As a dog returneth to his vomit, So a fool returneth to his folly. [12] Seest thou a man wise in his own conceit? There is more hope of a fool than of him.

‭2 Peter 2:20-22 KJV‬
[20] For if after they have escaped the pollutions of the world through the knowledge of the Lord and Saviour Jesus Christ, they are again entangled therein, and overcome, the latter end is worse with them than the beginning. [21] For it had been better for them not to have known the way of righteousness, than, after they have known it, to turn from the holy commandment delivered unto them. [22] But it is happened unto them according to the true proverb, The dog is turned to his own vomit again; and the sow that was washed to her wallowing in the mire.
