Theophylact of Ohrid, on 2Cor 11:29

“Who is weak, and I am not weak? Who is scandalized, and I am not on fire?”

“Then, how he expressed the excess of grief, for "I am inflamed," he says. Enduring everything else, he rejoiced, knowing that he endures for the Lord's sake; but here he is wounded in soul, so that the stumbling of another, even of an insignificant and rejected person, causes him great grief. And that the word "I am inflamed" must be understood in the sense of "I am caused to stumble," David teaches us. For just as the apostle said, "who is caused to stumble, for whom I would not be inflamed?" — so too David says exactly the same: when someone stumbles, I also appear as one who stumbles, and I strive to heal this sickness as my own. But where does David say this? In the words: "when the ungodly is proud, the poor is afflicted" (Ps. 9:23), that is, the poor person is caused to stumble when he comes to the thought that unworthy people abound in wealth and are exalted.”
