9:1-14 It is not new for a minister to meet with unkind returns for good-will to a people, and diligent and successful services among them. To the cavils of some, the apostle answers, so as to set forth himself as an example of self-denial, for the good of others. He had a right to marry as well as other apostles, and to claim what was needful for his wife, and his children if he had any, from the churches, without labouring with his own hands to get it. Those who seek to do our souls good, should have food provided for them. But he renounced his right, rather than hinder his success by claiming it. It is the people's duty to maintain their minister. He may wave his right, as Paul did; but those transgress a precept of Christ, who deny or withhold due support.
9. ox … treadeth … corn—(De 25:4). In the East to the present day they do not after reaping carry the sheaves home to barns as we do, but take them to an area under the open air to be threshed by the oxen treading them with their feet, or else drawing a threshing instrument over them (compare Mic 4:13).
Doth God … care for oxen?—rather, "Is it for the oxen that God careth?" Is the animal the ultimate object for whose sake this law was given? No. God does care for the lower animal (Ps 36:6; Mt 10:29), but it is with the ultimate aim of the welfare of man, the head of animal creation. In the humane consideration shown for the lower animal, we are to learn that still more ought it to be exercised in the case of man, the ultimate object of the law; and that the human (spiritual as well as temporal) laborer is worthy of his hire.
