{Have long hair} (kom(8369)). Present active subjunctive of
koma(935c) (from kom(885c), hair), old verb, same contraction
(-a(8869)=(8369)) as the indicative (aei = (8369)), but subjunctive here
with ean in third class condition. Long hair is a glory to a
woman and a disgrace to a man (as we still feel). The long-haired
man! There is a papyrus example of a priest accused of letting
his hair grow long and of wearing woollen garments. {For a
covering} (anti peribolaiou). Old word from periball(935c) to
fling around, as a mantle ( Heb 1:12 ) or a covering or veil as
here. It is not in the place of a veil, but answering to (anti,
in the sense of anti in  Joh 1:16 ), as a permanent endowment
(dedotai, perfect passive indicative).
