(Testament of the Twelve Patriarchs)
Hatred, therefore, is evil, for it constantly mateth with lying, speaking against the truth; and it maketh small things to be great, and causeth the light to be darkness, and calleth the sweet bitter, and teacheth slander, and kindleth wrath, and stirreth up war, and violence and all covetousness; it filleth the heart with evils and devilish poison. These things, therefore, I say to you from experience, my children, that ye may drive forth hatred, which is of the devil, and cleave to the love of God. Righteousness casteth out hatred, humility destroyeth envy. For he that is just and humble is ashamed to do what is unjust, being reproved not of another, but of his own heart, because the Lord looketh on his inclination. He speaketh not against a holy man, because the fear of God overcometh hatred. For fearing lest he should offend the Lord, he will not do wrong to any man, even in thought. These things I learnt at last, after I had repented concerning Joseph. For true repentance after a godly sort [destroyeth ignorance, and] driveth away the darkness, and enlighteneth the eyes, and giveth knowledge to the soul, and leadeth the mind to salvation.And those things which it hath not learnt from man, it knoweth through repentance. For God brought upon me a disease of the liver; and had not the prayers of Jacob my father succoured me, it had hardly failed but my spirit had departed, For by what things a man transgresseth, by the same also is he punished. Since, therefore, my liver was set mercilessly against Joseph, in my liver too I suffered mercilessly, and was judged for eleven months, for so long a time as I had been angry against Joseph.

2 Corinthians 7:5-12
8 For even if I made you sad by my letter, I do not regret having written it (even though I did regret it, for I see that my letter made you sad, though only for a short time). 9 Now I rejoice, not because you were made sad, but because you were made sad to the point of repentance. For you were made sad as God intended, so that you were not harmed in any way by us. 10For sadness as intended by God produces a repentance that leads to salvation, leaving no regret, but worldly sadness brings about death. 11 For see what this very thing, this sadness as God intended, has produced in you: what eagerness, what defense of yourselves, what indignation, what alarm, what longing, what deep concern, what punishment! In everything you have proved yourselves to be innocent in this matter. 12 So then, even though I wrote to you, it was not on account of the one who did wrong or on account of the one who was wronged, but to reveal to you your eagerness on our behalf before God.
