Proverbs 27:17-19

Expanded Bible

¹⁷ As iron sharpens iron,
so people ·can improve each other [sharpen their friends].

¹⁸ Whoever ·tends [protects] a fig tree gets to eat its fruit,
and whoever ·takes care of [guards] his master will receive honor.

¹⁹ As water reflects your face,
so ·your mind shows what kind of person you are [the heart reflects a person].
