⁷ He that reproveth a letz (mocker) getteth to himself shame, and he that is a mochiach (reprover) of a wicked man getteth himself a blot stain.

⁸ Reprove not a letz, lest he hate thee; rebuke a chacham, and he will love thee.

⁹ Give instruction to a chacham, and he will be yet wiser; teach a tzaddik, and he will increase in learning.
