Proverbs 27:17-19

New International Reader's Version

¹⁷ As iron sharpens iron,
    so one person sharpens another.

¹⁸ A person who guards a fig tree will eat its fruit.
    And a person who protects their master will be honored.

¹⁹ When you look into water, you see a likeness of your face.
    When you look into your heart, you see what you are really like.
