THE ACTS OF THE APOSTLES - Chapter 21 - Verse 23

Verse 23. We have four men. There are with us four men. It is evident that James and the elders meant to say, that these men were connected with them in the Christian church; and that act shows that the Christians at Jerusalem did not disregard the institutions of Moses, and had not been so far enlightened in the doctrines of Christianity as to forsake yet the ceremonial rites of the Jews.

Which have a vow on them. Which have made a vow. See Barnes "Ac 18:18".

From the mention of shaving the head, Ac 21:24, it is evident that the vow which they had taken was that of the Nazarite; and that as the time of their vow was about expiring, they were about to be shaven, in accordance with the custom usual on such occasions. See Barnes "Ac 18:18".

These persons Paul could join, and thus show decisively that he did not intend to undervalue or disparage the laws of Moses, when those laws were understood as mere ceremonial observances.
