1 Peter 3:11
10 For the one who wants to love life and see good days must keep his tongue from evil and his lips from uttering deceit. 11 And he must turn away from evil and do good; he must seek peace and pursue it. 12 For the eyes of the Lord are upon the righteous and his ears are open to their prayer. But the Lord’s face is against those who do evil.
Pirkei Avot 1:12
Mishnah11 Abtalion used to say: Sages be careful with your words, lest you incur the penalty of exile, and be carried off to a place of evil waters, and the disciples who follow you drink and die, and thus the name of heaven becomes profaned. 12 Hillel and Shammai received [the oral tradition] from them. Hillel used to say: be of the disciples of Aaron, loving peace and pursuing peace, loving mankind and drawing them close to the Torah. 13 He [also] used to say: one who makes his name great causes his name to be destroyed; one who does not add [to his knowledge] causes [it] to cease; one who does not study [the Torah] deserves death; one who makes [unworthy] use of the crown [of learning] shall pass away.
Notes and References
"... Besides the passages quoted directly from the Hebrew Bible, Hebrews includes a large number of allusions to certain stories or expressions, such as “consuming fire” (Hebrews 12:29, compare Deuteronomy 4:24); or “pursue peace with everyone” (Hebrews 12:14, compare Psalm 34:15), etc ... (The injunction “pursue peace” is a common motif of Old Testament and of later Jewish paraenesis. See Psalm 34:15; Testament of Simeon 5:2; Pirkei Avot 1:12; Matthew 5:9; 1 Peter 3:11, which cites Psalm 34:15 ...) ..."
