Proverbs 20:18

There is gold and abundance of rubies,

but the lips of knowledge are a rare jewel.

Take the garment of one who puts up collateral for a stranger;

and hold him in pledge for a wayward woman.

Fraudulent food is sweet to a man,

but afterwards his mouth is filled with gravel.

He who goes about as a tale-bearer reveals secrets;

therefore don’t keep company with him who opens wide his lips.

Whoever curses his father or his mother,

his lamp shall be put out in blackness of darkness.

An inheritance quickly gained at the beginning

won’t be blessed in the end.
