That I may be delivered from them that do not believe - He knew that his countrymen, who had not received the Gospel, lay in wait for his life; and, no doubt, they thought they should do God service by destroying him, not only as an apostate, in their apprehension, from the Jewish religion, but as one who was labouring to subvert and entirely destroy it.
And that my service - Διακονια . But several eminent MSS. read δωροφορια, the gift which I bear. This probably was a gloss, which in many MSS. subverted the word in the text; for διακονια, service, in its connection here, could refer to nothing else but the contribution which he was carrying to the poor saints at Jerusalem.
That I may be - The unbelieving Jews in Judea had been opposed to Paul‘s conversion. They could not forget that he had borne letters of commission from them to persecute the Christians at Damascus. They regarded him as an apostate. They had heard of his success among the Gentiles; and they had been informed that he “taught all the Jews among the Gentiles to forsake the laws of Moses;” Acts 21:21. Hence, the apostle could not but be aware that in returning to Judea, he exposed himself to special dangers. His fears, as the result showed, were well founded. They evinced all the opposition to him which he had ever anticipated; Acts 21:22-23, Acts 21:26-27.
(2) many of the converts from Judaism might be indisposed to receive an offering made by “Gentiles.” They might have retained many of their former feelings - that the Gentiles were polluted, and that they ought to have no fellowship with them. Early opinions and prejudices wear off by slow degrees. Christians retain former notions long after their conversion; and often many years are required to teach them enlarged views of Christian charity. It is not wonderful that the Christians in Judea should have been slow to learn all the ennobling lessons of Christian benevolence, surrounded as they were by the institutions of the Jewish religion, and having been themselves educated in the strictest regard for those institutions.
