Proverbs 20:15-17

Amplified Bible

¹⁵ 
There is gold, and an abundance of pearls,
But the lips of knowledge are a vessel of preciousness [the most precious of all].^(A)
16 
[The judge tells the creditor], “Take the clothes of one who is surety for a stranger;
And hold him in pledge [when he guarantees a loan] for foreigners.”^(B)
17 
Food gained by deceit is sweet to a man,
But afterward his mouth will be filled with gravel [just as sin may be sweet at first, but later its consequences bring despair].
