Rebuke

But now I am writing you not to associate with anyone who claims to be a brother but is sexually immoral or greedy, an idolater or a verbal abuser, a drunkard or a swindler. With such a man do not even eat. …

All Scripture is God-breathed and is useful for instruction, for conviction, for correction, and for training in righteousness,

You must not harbor hatred against your brother in your heart. Directly rebuke your neighbor, so that you will not incur guilt on account of him.

A rebuke cuts into a man of discernment deeper than a hundred lashes cut into a fool.

Brothers, if someone is caught in a trespass, you who are spiritual should restore him with a spirit of gentleness. But watch yourself, or you also may be tempted.

A wise son heeds his father’s discipline, but a mocker does not listen to rebuke.

…consider this: Whoever turns a sinner from the error of his way will save his soul from death and cover over a multitude of sins.

If your brother sins against you, go and confront him privately. If he listens to you, you have won your brother over.

Whoever loves discipline loves knowledge, but he who hates correction is stupid.
