Say I these things as a man? Lest any one should cavil, and say that in the things of the Lord the case is different, and therefore that he had to no purpose brought forward so many comparisons, he now adds, that the very same thing is commanded by the Lord. To speak as a man sometimes means -- speaking according to the perverse judgment of the flesh, (as in Romans 3:5.) Here, however, it means -- bringing forward only those things that are in common use among men, and are merely current (as they speak) in a human court. Now, that God himself designed that the labors of men should be remunerated by wages, he proves from this, that he prohibits the muzzling of the mouth of the ox that treadeth out the corn; and with the view of applying it to the subject in hand, he says, that God was not concerned as to oxen, but rather had regard to men. In the first place, it may be asked, Why has he more particularly selected this proof, while he had in the law passages that were much clearer? as for example, Deuteronomy 24:15, The wages of the hireling shall not remain with thee over night. If any one, however, will take a nearer view, he will acknowledge that there is more force in this quotation, in which the Lord requires cattle to be taken care of, for from this it is inferred, from the less to the greater, how much equity he requires among men, when he wishes that it should be shown to brute animals. When he says, that God does not take care for oxen, you are not to understand him as meaning to exclude oxen from the care of God's Providence, inasmuch as he does not overlook even the least sparrow. (Matthew 6:26, and Matthew 10:29.) Nor is it as if he meant to expound that precept allegorically, as some hair-brained spirits take occasion from this to turn everything into allegories. Thus they turn dogs into men, trees into angels, and turn all scripture into a laughing-stock. Paul's meaning is simple -- that, when the Lord enjoins humanity to oxen, he does not do it for the sake of oxen, but rather from a regard to men, on whose account, too, the very oxen were created. That compassion, therefore, towards oxen should be a stimulus to us to stir up to the exercise of humanity among us, as Solomon says, (Proverbs 12:10,) The righteous man hath a care over his beast, but the bowels of the wicked are cruel. Let it then be understood by you, that God is not so concerned for oxen, as to have had merely a regard to oxen in making that law, for he had mankind in view, and wished to accustom them to equity, that they might not defraud the workman of his hire. For it is not the ox that has the principal part in plowing or treading out the corn, but man, by whose industry the ox himself is set to work. Hence, what he immediately adds -- He that ploweth, should plow in hope, etc. is an exposition of the precept, as if he had said, that it extends generally to any kind of recompense for labor.

Say I these things as a man? - Do I speak this on my own authority, or without the sanction of God? Is not this, which appears to be so reasonable and equitable, also supported by the authority of God?
Or saith not the law the same also? - The Law of Moses, to which the "Jewish" part of the church at Corinth - which probably had mainly urged these objections - professed to bow with deference. Paul was accustomed, especially in arguing with the Jews, to derive his proofs from the Old Testament. In the previous verse he had shown that it was equitable that ministers of the gospel should be supported. In this and the following verses he shows that the same principle was recognized and acted on under the Jewish dispensation. He does not mean to say, by this example of the ox treading out the grain, that the law as given by Moses referred to the Christian ministry; but that the principle there was settled that the laborer should have a support, and that a suitable provision should not be withheld even from an ox; and if God so regarded the welfare of a brute when laboring, it was much more reasonable to suppose that he would require a suitable provision to be made for the ministers of religion.

Say I these things as a man? - Is this only human reasoning? or does not God say in effect the same things? See note on Romans 6:19.

(6) Say I these things (h) as a man? or saith not the law the same also?
(6) Secondly, he brings forth the authority of God's institution by an argument of comparison.
(h) Have I not better ground than the common custom of men?

Say I these things as a man?.... After the manner of men, reasoning from things common among men, and obvious to everyone's observation:
or saith not the law the same also? As the subject the apostle is upon was capable of being illustrated and confirmed by instances common unto, and easy of observation among men; so it might be supported by divine authority; it was not only a clear point from the reason of things, but was certain by the law of God.

as a man--I speak thus not merely according to human judgment, but with the sanction of the divine law also.

Do I speak as a man - Barely on the authority of human reason? Does not God also say, in effect, the same thing? The ox that treadeth out the corn - This was the custom in Judea, and many eastern nations. In several of them it is retained still. And at this day, horses tread out the corn in some parts of Germany.
