It is better to hear the rebuke of the wise, than for a man to hear the song of fools.
Preach the word; be instant in season, out of season; reprove, rebuke, exhort with all long suffering and doctrine. For the time will come when they will not endure sound doctrine; but after their own lusts shall they heap to themselves teachers, having itching ears; And they shall turn away their ears from the truth, and shall be turned unto fables.
Turn you at my reproof: behold, I will pour out my spirit unto you, I will make known my words unto you.
But to them that rebuke him shall be delight, and a good blessing shall come upon them.
Open rebuke is better than secret love.
Do not rebuke an older man but encourage him as you would a father, younger men as brothers, older women as mothers, younger women as sisters, in all purity.
