Acts 16:3

Him would Paul have to go forth with him--This is in harmony with all we read in the Acts and Epistles of Paul's affectionate and confiding disposition. He had no relative ties which were of service to him in his work; his companions were few and changing; and though Silas would supply the place of Barnabas, it was no weakness to yearn for the society of one who might become, what Mark once appeared to be, a son in the Gospel [HOWSON]. And such he indeed proved to be, the most attached and serviceable of his associates (Phi 2:19-23; Co1 4:17; Co1 16:10-11; Th1 3:1-6). His double connection, with the Jews by the mother's side and the Gentiles by the father's, would strike the apostle as a peculiar qualification for his own sphere of labor. "So far as appears, Timothy is the first Gentile who after his conversion comes before us as a regular missionary; for what is said of Titus (Gal 2:3) refers to a later period" [WIES]. But before his departure, Paul took and circumcised him--a rite which every Israelite might perform. because of the Jews . . . for they knew all that his father was a Greek--This seems to imply that the father was no proselyte. Against the wishes of a Gentile father no Jewish mother was, as the Jews themselves say, permitted to circumcise her son. We thus see why all the religion of Timothy is traced to the female side of the family (Ti2 1:5). "Had Timothy not been circumcised, a storm would have gathered round the apostle in his farther progress. His fixed line of procedure was to act on the cities through the synagogues; and to preach the Gospel to the Jew first and then to the Gentile. But such a course would have been impossible had not Timothy been circumcised. He must necessarily have been repelled by that people who endeavored once to murder Paul…

It is some rebuke to Barnabas that after he left Paul we hear no more of him, of what he did or suffered for Christ. But Paul, as he was recommended by the brethren to the grace of God, so his services for Christ after this are largely recorded; we are to attend him in this chapter from place to place, wherever he came doing good, either watering or planting, beginning new work or improving what was done. Here is, I. The beginning of his acquaintance with Timothy, and taking him to be his assistant (Act 16:1-3). II. The visit he made to the churches for their establishment (Act 16:4, Act 16:5). III. His call to Macedonia (after a restraint he had been under from going to some other places), and his coming to Philippi, the chief city of Macedonia, with his entertainment there (Act 16:6-13). IV. The conversion of Lydia there (Act 16:14, Act 16:15). V. The casing of an evil spirit out of a damsel (Act 16:16-18). VI. The accusing and abusing of Paul and Silas for it, their imprisonment, and the indignities done them (Act 16:19-24). VII. The miraculous conversion of the jailer to the faith of Christ (Act 16:25-34). VIII. The honourable discharge of Paul and Silas by the magistrates (Act 16:35-40).

16:3 Paul had Timothy circumcised to enhance Timothy’s acceptance and effectiveness as a Jew in Jewish circles (contrast Titus, who was a full Gentile, Gal 2:3). Elsewhere Paul clarified that it makes no difference to God whether one is circumcised or not circumcised (Rom 2:25-29; Gal 5:6; 6:15). Paul was prepared to use any legitimate means to communicate the Good News (1 Cor 9:20-21) to various audiences.
