52.

But it may be asked why, when it was said, "But I say unto you, Swear not at all," it was added, "neither by heaven, for it is God's throne," etc., up to "neither by thy head." I suppose it was for this reason, that the Jews did not think they were bound by the oath, if they had sworn by such things: and since they had heard it said, "Thou shalt perform unto the Lord thine oath," they did not think an oath brought them under obligation to the Lord, if they swore by heaven, or earth, or by Jerusalem, or by their head; and this happened not from the fault of Him who gave the command, but because they did not rightly understand it. Hence the Lord teaches that there is nothing so worthless among the creatures of God, as that any one should think that he may swear falsely by it; since created things, from the highest down to the lowest, beginning with the throne of God and going down to a white or black hair, are ruled by divine providence. "Neither by heaven," says He, "for it is God's throne; nor by the earth, for it is His footstool:" i.e., when you swear by heaven or the earth, do not imagine that your oath does not bring you under obligation to the Lord; for you are convicted of swearing by Him who has heaven for His throne, and the earth for His footstool. "Neither by Jerusalem, for it is the city of the great King;" a better expression than if He had said, "My [city];" although, however, we understand Him to have meant this. And, because He is undoubtedly the Lord, the man who swears by Jerusalem is bound by his oath to the Lord. "Neither shall thou swear by thy head." Now, what could any one suppose to belong more to himself than his own head? But how is it ours, when we have not the power of making one hair white or black? Hence, whoever should wish to swear even by his own head, is bound by his oath to God, who in an ineffable way keeps all things in His power, and is everywhere present. And here also all other things are understood, which could not of course be enumerated; just as that saying of the apostle we have mentioned, "By your rejoicing, I die daily." And to show that he was bound by this oath to the Lord, he has added, "which I have in Christ Jesus."
