Paul or Aquila?

Who is the subject of the first sentence, Paul, or his companions? This is the beginning of a five-verse paragraph, and throughout the rest of the passage, "he" is the predominant pronoun. One, since Paul is the subject of the first sentence of a paragraph and "he" would not referred to a married couple -- which is how Priscilla and Aquila are introduced secondarily, and remain so -- and two, given that Dr. Luke is primarily recounting Paul's ministry here, it is obvious the reference is to Paul. The way the KJV renders it does make it unclear, I suppose, but it is quite clear in other versions. The one with the vow is Paul.

 

Did not the days of purification require shaved heads?

Paul, being a Jew, and desiring to present himself respectfully to Jews, would have shaved his head.

Imo, it really hasn't much to do with legalism as it was getting an opportunity to witness without offense.

Sort of like one not eating garlic and onions or not taking a bath after working up a sweat before going out witnessing about Christ.

 

He was warned not to go:

3 And when we had come in sight of Cyprus, leaving it on the left hand, we sailed unto Syria, and landed at Tyre; for there the ship was to unlade her burden.
4 And having found the disciples, we tarried there seven days: and these said to Paul through the Spirit, that he should not set foot in Jerusalem.
10 And as we tarried there some days, there came down from Judaea a certain prophet, named Agabus.
11 And coming to us, and taking Paul`s girdle, he bound his own feet and hands, and said, Thus saith the Holy Spirit, So shall the Jews at Jerusalem bind the man that owneth this girdle, and shall deliver him into the hands of the Gentiles.
12 And when we heard these things, both we and they of that place besought him not to go up to Jerusalem. Acts 21
