2 Peter 2:21-22

21For ait would have been better for them never to have known the way of righteousness than after knowing it to turn back from bthe holy commandment delivered to them. 22What the true proverb says has happened to them: “The cdog returns to its own vomit, and the sow, after washing herself, returns to wallow in the mire.”

1 John 2:19

19 dThey went out from us, but they were not of us; for eif they had been of us, they would have continued with us. But they went out, fthat it might become plain that they all are not of us.
