4:17 They zealously affect you, {q} [but] not well; yea, they would exclude you, {r} that ye might affect them.
(q) For they are jealous over you for their own benefit.
(r) That they may transfer all your love from me to themselves.
4:17 They zealously affect you, [but] not well. The false, Judaizing teachers are meant. They showed great zeal for them, but they were not seeking their good.
Yea, they would exclude you, that ye might affect them. Exclude you from the great body of Gentile believers and bind you to their clique.
4:17 They - The judaizing teachers who are come among you. Zealously affect you - Express an extraordinary regard for you. But not well - Their zeal is not according to knowledge; neither have they a single eye to your spiritual advantage. Yea, they would exclude you - From me and from the blessings of the gospel. That ye might affect - Love and esteem them.
4:12-18 The apostle desires that they would be of one mind with him respecting the law of Moses, as well as united with him in love. In reproving others, we should take care to convince them that our reproofs are from sincere regard to the honour of God and religion and their welfare. The apostle reminds the Galatians of the difficulty under which he laboured when he first came among them. But he notices, that he was a welcome messenger to them. Yet how very uncertain are the favour and respect of men! Let us labour to be accepted of God. You once thought yourselves happy in receiving the gospel; have you now reason to think otherwise? Christians must not forbear speaking the truth, for fear of offending others. The false teachers who drew the Galatians from the truth of the gospel were designing men. They pretended affection, but they were not sincere and upright. An excellent rule is given. It is good to be zealous always in a good thing; not for a time only, or now and then, but always. Happy would it be for the church of Christ, if this zeal was better maintained.
