But I speak this by permission,.... Referring either to what he had said before, though not to all; not to 1Co 7:2 that for the avoiding of fornication, every man should make use of his own wife, and every woman of her own husband; since this is not by permission, but by command, Ge 2:24 that carnal copulation should be between one man and one woman in a married state; nor to 1Co 7:3 for that married persons ought to render due benevolence to, and not defraud each other, having a power over each other's bodies, is a precept, and not a permission, Ex 21:10 but to 1Co 7:5 their parting for a time, and coming together again: it is not an absolute command of God that they should separate for a time, on account of fasting and prayer, but if they thought fit to do so by agreement, they might; nor was there any positive precept for their coming together again directly, after such service was over.
The apostle said this,not of commandment; but, consulting their good, gives this advice, lest Satan should be busy with them, and draw them into sin; but if they had the gift of continence, they might continue apart longer; there was no precise time fixed by God, nor did the apostle pretend to fix any: or it may refer to what follows after, that he would have all men be as he was; though he laid no injunction, but left them to their liberty; unless it can be thought to regard marriage in general, and to be said in opposition to a Jewish notion, which makes marriage hwum, a "command";"a man, they say , is bound to this command at seventeen years of age, and if he passes twenty and does not marry, he transgresses, and makes void an affirmative precept;''but the apostle puts it as a matter of choice, and not of obligation.
