MNT(i)
20 For if, after having escaped the pollutions of the world, through the knowledge of our Lord and Saviour Jesus Christ, men are again entangled in them and overpowered, their last state is become worse than their first.
21 Indeed it would have been better for them not to have known the Way of Righteousness, than, after knowing it, to turn back from the holy command delivered to them.
22 In their case it has happened according to the true proverb, The dog returns again to his own vomit, and The sow, after washing, to her wallowing in the mire.
