18 He who tends a fig tree will eat its fruit, and he who guards his master will be honored.
19 As the waters reflect face to face, so the heart of a person reflects the person.
20 Sheol and Abaddon will not be satisfied, and the eyes of a person will not be satisfied either.
21 A crucible is for the silver, and a furnace for the gold, but a man is tested by the mouth of him who praises him.
22 If you crush a fool in the mortar with the pestle along with the crushed grain, it will not drive folly from upon him.
23 You will surely know the condition of your flock; your heart attends to the herds.
