Mattityahu 5:37-39

Orthodox Jewish Bible

³⁷ But let your word be ken, ken (yes, yes) or lo, lo (no, no), but anything beyond this is lashon horah.

³⁸ You have heard that it was said, AYIN TACHAT AYIN, SHEN TACHAT SHEN (An eye for an eye and a tooth for a tooth SHEMOT 21:24).

³⁹ But I say to you, Do not set yourself against the rasha (evil person), but whoever hits you on your right cheek, turn to him also the other cheek.
