17 ⌊As⌋ iron sharpens iron,so one person sharpens the wits of another.
18 Whoever takes care of a fig tree can eat its fruit,and whoever protects his master is honored.
19 As a face is reflected in water,so a person is reflected by his heart.
20 Hell and decay are never satisfied,and a person’s eyes are never satisfied.
21 The crucible is for refining silver and the smelter for gold,but a person ⌊is tested⌋ by the praise given to him.
22 If you crush a stubborn fool in a mortar with a pestle along with grain,⌊even then⌋ his stupidity will not leave him.
23 Be fully aware of the condition of your flock,and pay close attention to your herds.
