Proverbs 27:16-18

Amplified Bible

¹⁶ 
Whoever attempts to restrain her [criticism] might as well try to stop the wind,
And grasps oil with his right hand.
¹⁷ 
As iron sharpens iron,
So one man sharpens [and influences] another [through discussion].
¹⁸ 
He who tends the fig tree will eat its fruit,
And he who faithfully protects and cares for his master will be honored.^(A)
