Luke 17:3

Thou shalt not hate thy brother in thine heart: thou shalt in any wise rebuke thy neighbour, and not suffer sin upon him.

Then came Peter to him, and said, Lord, how oft shall my brother sin against me, and I forgive him? till seven times?

Reprove not a scorner, lest he hate thee: rebuke a wise man, and he will love thee.

Moreover if thy brother shall trespass against thee, go and tell him his fault between thee and him alone: if he shall hear thee, thou hast gained thy brother. But if he will not hear thee, then take with thee one or two more, that in the mouth of two or three witnesses every word may be established. And if he shall neglect to hear them, tell it unto the church: but if he neglect to hear the church, let him be unto thee as an heathen man and a publican.

Brethren, if any of you do err from the truth, and one convert him;

And said to the judges, Take heed what ye do: for ye judge not for man, but for the Lord, who is with you in the judgment. Wherefore now let the fear of the Lord be upon you; take heed and do it: for there is no iniquity with the Lord our God, nor respect of persons, nor taking of gifts.

Open rebuke is better than secret love.

Take heed unto yourselves, lest ye forget the covenant of the Lord your God, which he made with you, and make you a graven image, or the likeness of any thing, which the Lord thy God hath forbidden thee.

Only take heed to thyself, and keep thy soul diligently, lest thou forget the things which thine eyes have seen, and lest they depart from thy heart all the days of thy life: but teach them thy sons, and thy sons’ sons;

Take heed to thyself, lest thou make a covenant with the inhabitants of the land whither thou goest, lest it be for a snare in the midst of thee:

Look to yourselves, that we lose not those things which we have wrought, but that we receive a full reward.

See then that ye walk circumspectly, not as fools, but as wise,

Looking diligently lest any man fail of the grace of God; lest any root of bitterness springing up trouble you, and thereby many be defiled;

And take heed to yourselves, lest at any time your hearts be overcharged with surfeiting, and drunkenness, and cares of this life, and so that day come upon you unawares.

A reproof entereth more into a wise man than an hundred stripes into a fool.

Let the righteous smite me; it shall be a kindness: and let him reprove me; it shall be an excellent oil, which shall not break my head: for yet my prayer also shall be in their calamities.

Take ye therefore good heed unto yourselves; for ye saw no manner of similitude on the day that the Lord spake unto you in Horeb out of the midst of the fire:

But when Peter was come to Antioch, I withstood him to the face, because he was to be blamed. For before that certain came from James, he did eat with the Gentiles: but when they were come, he withdrew and separated himself, fearing them which were of the circumcision. And the other Jews dissembled likewise with him; insomuch that Barnabas also was carried away with their dissimulation. But when I saw that they walked not uprightly according to the truth of the gospel, I said unto Peter before them all, If thou, being a Jew, livest after the manner of Gentiles, and not as do the Jews, why compellest thou the Gentiles to live as do the Jews?
