Galatians 4:16

So then am I become your enemy, by telling you the truth? [I beseech you, brethren, become as I am, and be not Jews; for I forsook Judaism and became simply a Christian, which made me, in the eyes of my brethren, a Gentile like you. Though I have spoken severely to you, it is for no personal reasons. Ye have done me no wrong. On the contrary, your actions have been very gracious, for you will remember (and here the apostle refers to facts that are nowhere recorded, but which we presume to run thus:) that my journeying was providentially delayed as I was passing through your land, by my sickness; and so it came about that I preached the gospel unto you; and though my sickness was of so revolting a nature that ye might well have yielded to the temptation to ridicule or despise me, and reject me because of it, ye did not; for, conversely, ye received me as if I had been an angel of light, or the Lord himself. What, then, has become of your self-gratulation that you felt at having a real apostle among you? for I bear you witness that you so honored me that you would have plucked out your very eyes for my sake. Am I then showing myself to be your enemy by telling you truly how foolishly you are conducting yourselves? This plucking out of the eyes for another was a proverbial expression, indicating extreme attachment, and we have so rendered it in the paraphrase. Many take this as an indication that Paul's thorn in the flesh was ophthalmia; see 2 Corinthians 12:7 and note; and this is not improbable, for, though the expression is proverbial, Paul does not here state it in proverbial form. The words "given them to me" suggest that he needed eyes, and these words are not essential to the proverb.]
