Proverbs 20:15-17

¹⁵There is gold, and a multitude of rubies; but the lips of knowledge are a precious jewel.

¹⁶Take his garment that is surety for a stranger; and hold him in pledge that is surety for an alien woman.

¹⁷Bread of falsehood is sweet to a man; but afterwards his mouth shall be filled with gravel.
