Found in Mt. 19:4; Mk. 10:6; Lk. 2:23; Rom. 1:27; Gal. 3:28; Rev. 12:5, 13, the Greek adjective “arsen” meant “man” or “male.” The Exegetical Dictionary of the New Testament  (1:158) noted how this term “literally means that which discharges sperm and therefore male offspring, male child.”

This word is virtually synonymous with “aner,” another word for “male,” and in some manuscripts for Rom. 1:27; Rev. 12:5, 13, we find the adjective “arrhen” instead of “arsen.”
