17 As iron sharpens iron,
so one person sharpens another.
18 The one who guards a fig tree will eat its fruit,
and whoever protects their master will be honored.
19 As water reflects the face,
so one’s life reflects the heart.[a]
20 Death and Destruction[b] are never satisfied,
and neither are human eyes.
21 The crucible for silver and the furnace for gold,
but people are tested by their praise.
