1 Corinthians 9:7-14

He argues it out of the Jewish law: Say I these things as a man? Or saith not the law the same also? 1 Cor. 9:8. Is this merely a dictate of common reason and according to common usage only? No, it is consonant to the old law. God had therein ordered that the ox should not be muzzled while he was treading out the corn, nor hindered from eating while he was preparing the corn for man’s use, and treading it out of the ear. But this law was not chiefly given out of God’s regard to oxen, or concern for them, but to teach mankind that all due encouragement should be given to those who are employed for us, or labouring for our good—that the labourers should taste of the fruit of their labours. Those who plough should plough in hope; and those who thresh in hope should be partakers of their hope, 1 Cor. 9:10. The law saith this about oxen for our sakes. Note, those that lay themselves out to do our souls good should not have their mouths muzzled, but have food provided for them.
