1 Corinthians 7:6

By way of permission (kata sungnwmhn). 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 epitaghn). Late word (in papyri) from epitassw, old word to enjoin. Paul has not commanded people to marry. He has left it an open question.
