Proverbs 27:17

15 A constant dripping on a rainy day and a contentious woman are alike—

16 restraining her is like holding back the wind or grasping oil with one’s right hand.

As iron sharpens iron, so one man sharpens another.

18 Whoever tends a fig tree will eat its fruit, and he who looks after his master will be honored.

19 As water reflects the face, so the heart reflects the true man.

Do read the surrounding verses too, because the context often says more than a single verse.
