μή
mḗ · word · “not, lest”
Mē is one of Greek's two words for "not" — the subjective negation used in commands, prayers, and possibilities. "Do not (mē) be anxious about anything."
Mē negates wishes, commands, and contingent statements, while ou negates plain fact. Greek thus distinguishes "is not" from "let it not be."
Many of the New Testament's great imperatives turn on mē: do not fear, do not be anxious, do not let your hearts be troubled. Mē genoito ("may it never be!") is Paul's explosive denial in Romans.
