2 Peter 2:21-22

Young's Literal Translation

²¹ for it were better to them not to have acknowledged the way of the righteousness, than having acknowledged [it], to turn back from the holy command delivered to them,

²² and happened to them hath that of the true similitude; `A dog did turn back upon his own vomit,' and, `A sow having bathed herself -- to rolling in mire.'
