레위기 19:17의 주석

ולא תשא עליו חטא [THOU SHALT IN ANY WISE REBUKE THY COMPANION] AND NOT BEAR A SIN ON ACCOUNT OF HIM — i. e. though rebuking him thou shalt not expose him to shame (lit., make his face grow pale) in public, in which case you will bear sin on account of him (cf. Sifra, Kedoshim, Chapter 4 8; Arakhin 16b).

THOU SHALT NOT HATE THY BROTHER IN THY HEART. Because it is the way of those who hate a person to cover up their hatred in their hearts, just as it is said, He that hateth dissembleth with his lips, but he layeth up deceit within him,⁸³Proverbs 26:24. therefore Scripture speaks of the usual events, [mentioning, thou shalt not hate thy brother ‘in thy heart,’ but the law forbids all hating, even if done openly]. THOU SHALT SURELY REBUKE THY NEIGHBOR, This constitutes another commandment, that we must teach him reproof of instruction.⁸⁴Proverbs 6:23. For the commandment is a lamp, and the teaching is light, and reproofs of instruction are a way of life. See “The Commandments,” Vol. I, pp. 219-220. THOU SHALT NOT BEAR SIN BECAUSE OF HIM, for you will bear sin because of his transgression if you do not rebuke him. Onkelos’ rendition tends towards this explanation, for he translated, “and do not receive guilt because of him,” meaning that you should not be punished by his sin. Following these commandments He then said [in the following verse] that you are to love your neighbor. Thus he who hates his neighbor violates a negative commandment, and he who loves him, fulfills a positive commandment.
The correct interpretation appears to me to be that the expression ‘hochei’ach tochiach’ (thou shalt surely rebuke), is similar to ‘V’hochiach Avraham’ (And Abraham reproved) Abimelech.⁸⁵Genesis 21:25. The verse here is thus stating: “do not hate your brother in your heart when he does something to you against your will, but instead you are to reprove him, saying, ‘Why did you do thus to me?’ and you will not bear sin because of him by covering up your hatred of him in your heart and not telling him, for when you will reprove him, he will justify himself before you [so that you will have no cause to hate him], or he will regret his action and admit his sin, and you will forgive him.” After that He admonishes [in the following verse] that you are not to take vengeance of him, nor bear a grudge in your heart against him because of what he has done to you, for it is possible that he will not hate him, but yet he will remember in his heart his neighbor’s sin against him; therefore He admonished him that he is to erase his brother’s sin and transgression against him from his heart. Following that admonition, He commanded that he love him as himself.

לא תשנא את אחיך בלבבך, "do not hate your brother in your heart, etc." The Torah urges us that if we harbour some resentment against a fellow Jew not to bottle it up in one's heart saying nothing but hating the Jew in question. One has to come out with one's feelings into the open, בפיך, and rebuke the person who one thinks as guilty of having bad-mouthed him or otherwise hurt him to cause such hatred. הוכח תוכיח, "rebuke him, even repeatedly," ולא תשא עליו חטא, "so that you will not bear a sin on account of him." Do not assume in your heart that whatever it is the other Jew has done to cause you to hate him he has done purposely and that he continues to feel hostile towards you. Give him the benefit of the doubt and discuss the matter with him. The discussion could lead to one of two possible results. 1) He may explain to you that he had a good reason for what he did so that there is no reason to hate him. 2) He may change his attitude towards you, undertaking not to continue his hostile conduct. As a result he becomes "your friend, your brother."
