"Whosoever hateth his brother is a murderer: and ye know that no murderer hath eternal life abiding in him." — 1 John 3:15 (ASV)

A murderer (ανθρωποκτονος). Old compound (Euripides) from ανθρωπος (man) and κτεινω (to kill), a man-killer, in N.T. only here and Joh 8:44 (of Satan).

No (πασ--ου). According to current Hebraistic idiom= ουδεις as in 2:19,21.

Abiding (μενουσαν). Present active feminine accusative predicate participle of μενω, "a continuous power and a communicated gift" (Westcott).
