2 Peter 2:21-22

Darby Translation

²¹ For it were better for them not to have known the way of righteousness, than having known [it] to turn back from the holy commandment delivered to them.

²² But that [word] of the true proverb has happened to them: [The] dog [has] turned back to his own vomit; and, [The] washed sow to [her] rolling in mud.
