And sware one to another. Isaac does not hesitate to swear; partly, that the Philistines may be the more easily appeased; partly, that he may not be suspected by them. And this is the legitimate method of swearing, when men mutually bind themselves to the cultivation of peace. A simple promise, indeed, ought to have sufficed; but since dissimulations or inconstancy causes men to be distrustful of each other, the Lord grants them the use of his name, that this more holy confirmation may be added to our covenants; and he does not only permit, he even commands us to swear as often as necessity requires it. (Deuteronomy 6:13.) Meanwhile we must beware, lest his name be profaned by rashly swearing.
They rose up be times - Early rising was general among the primitive inhabitants of the world, and this was one cause which contributed greatly to their health and longevity.
And they rose up betimes in the morning,.... Abimelech and his friends, in order to return home, and Isaac to take his leave of them, and both to make the covenant between them in form, and confirm it by an oath, for which the morning was the fitter time; when the mind is quite free and composed, and attentive to what is done, as so solemn a transaction should be performed with the utmost attention and seriousness:
and swore one to another; to live in amity and friendship, and not distress and disturb each other:
and Isaac sent them away, and they departed from him in peace; he took his leave of them in a friendly manner, and they departed well pleased with the reception they had met with, and the success they had had, having agreed on and settled articles of peace to mutual satisfaction.
