2 Peter 2:20-22

Twentieth_Century(i) 20 If, after having escaped the polluting influences of the world, through knowing our Lord and Savior, Jesus Christ, men are again entangled in them, and give way to them, their last state has become worse than their first. 21 It would, indeed, have been better for them not to have known the Way of Righteousness, than, after knowing it, to turn away from the holy Command delivered to them. 22 In their case is seen the truth of the proverb-- 'A dog returns to what he has vomited' and 'A sow after washing to her wallowing-place in the mud.'
