1 Corinthians 7:6

This. It is impossible to determine how much this pronoun is intended to cover, whether only the suggestion in v. 5 or the entire instruction in vs. 1-5.

By permission. Gr. suggnome, “agreement,” “mutual opinion or judgment,” “concession.” He does not intend to give the impression that married persons are under obligation to practice varying periods of abstinence by mutual agreement. He simply explains that if they so desire, they are perfectly free to enter into such an arrangement; they are not commanded to do so. This expression does not require the conclusion that Paul was not inspired by the Holy Spirit when he gave the advice found in v. 5. If vs. 1-5 are under consideration here, then Paul is further saying that he is not making the matter of whether to get married, one of command. This is a matter for the individual to decide.
