Proverbs 20:14-17

¹⁴A poor thing, a poor thing, says he who is giving money for goods: but when he has gone on his way, then he makes clear his pride in what he has got.

¹⁵There is gold and a store of corals: but the lips of knowledge are a jewel of great price.

¹⁶Take a man's clothing if he makes himself responsible for a strange man, and get an undertaking from him who gives his word for strange men.

¹⁷Bread of deceit is sweet to a man; but after, his mouth will be full of sand.
