Galatians 1:9

“As we have said before, so say I now again, etc..] Either when he first preached the Gospel among them; or rather referring to what he had just now said, which he repeats with some little alteration; as if any, men, or angels, be they of what name, figure, rank, or office whatever, preach any other Gospel unto you, than that ye have received; and as the apostle thought, readily, willingly, sincerely, and heartily, in the love of it; assenting to the truth, feeling the power of it, and openly professing it: let him be accursed; which he repeats, for the more solemn asseveration and confirmation of it; and to show that this did not drop from his lips hastily and inadvertently; nor did it…”

“said before--when we were visiting you (so "before" means, Co2 13:2). Compare Gal 5:2-3, Gal 1:21. Translate, "If any man preacheth unto you any gospel BESIDE that which," &c. Observe the indicative, not the subjunctive or conditional mood, is used, "preacheth," literally, "furnisheth you with any gospel." The fact is assumed, not merely supposed as a contingency, as in Gal 1:8, "preach," or "should preach." This implies that he had already observed (namely, during his last visit) the machinations of the Judaizing teachers: but his surprise (Gal 1:6) now at the Galatians being misled by them, implies that they had not apparently been so then. As in Gal 1:8 he had said, "which we preached,"…”

“As we said before - That is, in the previous verse. It is equivalent to saying, “as I have just said;” see 2 Corinthians 7:3. It cannot be supposed that he had said this when he was with them, as it cannot be believed that he then anticipated that his doctrines would be perverted, and that another gospel would be preached to them. The sentiment of Galatians 1:8 is here repeated on account of its importance. It is common in the Scriptures, as indeed it is everywhere else, to repeat a declaration in order to deepen the impression of its importance and its truth. Paul would not be misunderstood on this point. He would leave no doubt as to his meaning. He would not have it supposed that he had…”

“As - He speaks upon mature deliberation; after pausing, it seems, between the two verses. We - I and the brethren who are with me. Have said before - Many times, in effect, if not in terms. So I say - All those brethren knew the truth of the gospel. St. Paul knew the Galatians had received the true gospel. Galatians 1:10”

“1:9 The Good News . . . you welcomed was precisely the message Paul had preached to them (1:8; cp. 2 Thes 2:15).”

“so: Co2 1:17, Co2 13:1, Co2 13:2; Phi 3:1, Phi 4:4 than: Deu 4:2, Deu 12:32, Deu 13:1-11; Pro 30:6; Rev 22:18, Rev 22:19 Galatians 1:10”
