{By way of permission} (kata sungn(936d)(886e)). Old word for
pardon, concession, indulgence. _Secundum indulgentiam_
(Vulgate). Only here in N.T., though in the papyri for pardon.
The word means "knowing together," understanding, agreement, and
so concession. {Not of commandment} (ou kat' epitag(886e)). Late
word (in papyri) from epitass(935c), old word to enjoin. Paul has
not commanded people to marry. He has left it an open question.
