'Again' in the Bible

For if, after they have escaped the pollutions of the world by [personal] knowledge of our Lord and Savior Jesus Christ, they are again entangled in them and are overcome, their last condition has become worse for them than the first.

The thing spoken of in the true proverb has happened to them, “The dog returns to his own vomit,” and, “A sow is washed only to wallow [again] in the mire.”
