Proverbs 27:18-21

¹⁸He that plants a fig tree shall eat the fruits of it: so he that waits on his own master shall be honoured.

¹⁹As faces are not like other faces, so neither are the thoughts of men.

²⁰Hell and destruction are not filled; so also are the eyes of men insatiable. He that fixes his eye is an abomination to the Lord; and the uninstructed do not restrain their tongue.

²¹Fire is the trial for silver and gold; and a man is tried by the mouth of them that praise him. The heart of the transgressor seeks after mischiefs; but an upright heart seeks knowledge.
