(יח) לֹֽא־תִקֹּ֤ם וְלֹֽא־תִטֹּר֙ אֶת־בְּנֵ֣י עַמֶּ֔ךָ וְאָֽהַבְתָּ֥ לְרֵעֲךָ֖ כָּמ֑וֹךָ אֲנִ֖י יְהֹוָֽה׃
(18) You shall not take vengeance or bear a grudge against your countrymen. Love your fellow as yourself: I am the LORD.
(ב) ואהבת לרעך כמוך. אָמַר רַבִּי עֲקִיבָא זֶה כְּלָל גָּדוֹל בַּתּוֹרָה (ספרא):
(2) ואהבת לרעך כמוך THOU SHALT LOVE THY FELLOW MAN AS THYSELF —Rabbi Akiba said: “This is a fundamental principle of the Torah” (Sifra, Kedoshim, Chapter 4 12; Talmud Yerushalmi Nedarim 9:3).
(ג) ואהבת לרעך כמוך - רעך הוא אם טוב [הוא], אבל לא אם הוא רשע, כדכתיב: יראת ה' שנאת רע.
(3) ואהבת לרעך כמוך, if he is truly your colleague, friend; however, if he is wicked you need not love him, as even G’d hates him as we know from Proverbs 8,13 יראת ה' שנאת רע, “to fear the Lord is to hate evil.” (compare Pessachim 113)
(3) We read in Leviticus 19,18, "Love your fellow man like yourself." This teaches that all love is measured against the yardstick of self love. Time is measured in terms of the revolution of the earth around its own axis. A complete revolution equals a day. All other measurements of time are fractions of a day. Similarly, love for one's fellow man is measured by how nearly it equals the love one feels for oneself.
