עֹזְבֵ֣י ת֭וֹרָה יְהַֽלְל֣וּ רָשָׁ֑ע וְשֹׁמְרֵ֥י ת֝וֹרָ֗ה יִתְגָּ֥רוּ בָֽם׃ (פ)
율법을 버린 자는 악인을 칭찬하나 율법을 지키는 자는 악인을 대적하느니라
Megillah
Is this so? But did not R. Yohanan say in the name of R. Shimon b. Yohai: It is permitted to contend with the wicked in this world, as it says, “They that forsake the law praise the wicked, but such as keep the law contend with them” (Proverbs 28:4). Also it has been taught: R. Dostai b. Maton says: It is permitted to contend with the wicked in this world. And if one should whisper to you saying, “Do not contend with evildoers, neither be envious against those that do acts of unrighteousness,” one whose conscience smites him is saying this.
Berakhot
R. Johanan also said in the name of R. Simeon b. Johai : It is permissible to contend with the wicked in this world; as it is said, "They that forsake the law praise the wicked, but such as keep the law contend with him" (Prov. xxviii, 4).
