εἰνάκις
From LSJ
καὶ οὐκ ἐκδικᾶταί σου ἡ χείρ, καὶ οὐ μηνιεῖς τοῖς υἱοῖς τοῦ λαοῦ σου καὶ ἀγαπήσεις τὸν πλησίον σου ὡς σεαυτόν· ἐγώ εἰμι κύριος. Τὸν νόμον μου φυλάξεσθε → Let your hand not seek vengeance; do not show wrath toward the children of your people; love your neighbor as yourself. I am the Lord! Keep my Torah! (Leviticus 19:18f. LXX)
