The Apostle Paul
1 Corinthians 4:12BSB·traditional attribution

We work hard with our own hands. When we are vilified, we bless; when we are persecuted, we endure it;

John Calvin Reformed @genevareformer

12. When he says that while persecuted he suffers it, and that he prays for his revilers, he intimates that he is not merely afflicted and abased by God, by means of the cross, but is also endowed with a disposition to abase himself willingly.

Matthew Henry Presbyterian @wholebiblehenry

Here the apostle improves the foregoing hint to a caution against pride and self-conceit, and sets forth the temptations the Corinthians had to despise him, from the difference of their circumstances. I. He cautions them against pride and self-conceit by this consideration, that all the distinction made among them was owing to God: Who maketh thee to differ? And what hast thou that thou didst not receive? Co1 4:7.

John Gill Reformed Baptist @doctorgill

And labour, working with our own hands,.... As the apostle did at Corinth, Act 18:3 and elsewhere; partly to minister to his own necessities, and those of others; and partly that he might not be burdensome to the churches; and also to set an example of diligence and industry to others; though he had a right and power to claim a maintenance of those to whom he ministered.
