Proverbs 27:18-22

One who tends the fig tree will eat its fruit, And one who cares for his master will be honored.

As in water a face reflects the face, So the heart of a person reflects the person.

Sheol and Abaddon are never satisfied, Nor are the eyes of a person ever satisfied.

The crucible is for silver and the furnace for gold, And each is tested by the praise accorded him.

Though you pound the fool in a mortar with a pestle along with crushed grain, His foolishness still will not leave him.
