Proverbs 24:28

26 An honest answer given is like a kiss on the lips.

27 Complete your outdoor work and prepare your field; after that, you may build your house.

Do not testify against your neighbor without cause, and do not deceive with your lips.

29 Do not say, “I will do to him as he has done to me; I will repay the man according to his work.”

30 I went past the field of a slacker and by the vineyard of a man lacking judgment.

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