“And as they went through the cities, they delivered them the decrees for to keep, that were ordained of the apostles and elders which were at Jerusalem.”
King James Version (KJV)
16:3 He took and circumcised him because of the Jews - The unbelieving Jews, to whom he designed he should preach. For they would not have conversed with him at all, so long as he was uncircumcised.
16:6 And having gone through Phrygia - And spoken there what was sufficient, as well as in the region of Galatia, being forbid by the Spirit (probably by an inward dictate) to speak as yet in the proconsular Asia, the time for it not being come.
Ac 16:4,5 They went through the cities. Where churches were already planted. As they went, they "delivered the decrees" on circumcision and the law of Moses decided upon at Jerusalem (Ac 15:23-29).
