Proverbs 16:25-27

²⁵There are ways that seem to be right to a man, but the end of them looks to the depth of hell.

²⁶A man who labours, labours for himself, and drives from him his own ruin.

²⁷But the perverse bears destruction upon his own mouth: a foolish man digs up evil for himself, and treasures fire on his own lips.
