James Version (KJV) Acts 15

1 And certain men which came down from Judaea taught the brethren, and said, Except ye be circumcised after the manner of Moses, ye cannot be saved.

2 When therefore Paul and Barnabas had no small dissension and disputation with them, they determined that Paul and Barnabas, and certain other of them, should go up to Jerusalem unto the apostles and elders about this question.

John Gill writes...

should go up to Jerusalem, unto the apostles and elders, about this question; concerning circumcision, and the necessity of it to salvation, that they might have the sense of James, and Peter, and John, who particularly were at Jerusalem at this time, as appears from Act 15:7 and other apostles that might be there; and also of other ministers of the word, who are called elders. And the church of Jerusalem being the most ancient church, and several of the apostles residing here, who had seen Christ in the flesh, and had received their mission and commission from him, and had been extraordinarily endowed with the Holy Ghost; and here being many other preachers of the Gospel, and there being in a multitude of counsellors safety, the church at Antioch judged it advisable to send to them for counsel and direction; and it becomes churches to assist each other in this way.

Note these are mentioned a number of times here in Acts.

Act 15:2 When therefore Paul and Barnabas had no small dissension and disputation with them, they determined that Paul and Barnabas, and certain other of them, should go up to Jerusalem unto the apostles and elders about this question.

Act 15:4 And when they were come to Jerusalem, they were received of the church, and of the apostles and elders, and they declared all things that God had done with them.

Act 15:6 And the apostles and elders came together for to consider of this matter.

Act 15:22 Then pleased it the apostles and elders, with the whole church, to send chosen men of their own company to Antioch with Paul and Barnabas; namely, Judas surnamed Barsabas, and Silas, chief men among the brethren:

Act 15:23 And they wrote letters by them after this manner; The apostles and elders and brethren send greeting unto the brethren which are of the Gentiles in Antioch and Syria and Cilicia:

Act 16:4 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.

Btw this chapter also refers to prophets in two senses..

Act 15:14 Simeon hath declared how God at the first did visit the Gentiles, to take out of them a people for his name.

Act 15:15 And to this agree the words of the prophets; as it is written,

Acts 15:15 Gill

And to this agree the words of the prophets,.... In several of the prophecies of the Old Testament, which plainly speak of the calling of the Gentiles; though James thought it sufficient to produce only one instead of many:

as it is written; in Amo 9:11 and this is agreeably to the Jewish way of citing Scriptures, as Surenhusius observes; so it is said (q), in twenty four places the priests are called Levites, and this is one of them, Eze 44:15 where only one place is mentioned, instead of the twenty four.

(q) T. Bab. Yebamot, fol. 86, 2. & Beracot, fol. 4. 1, 2.

Act 15:16 After this I will return, and will build again the tabernacle of David, which is fallen down; and I will build again the ruins thereof, and I will set it up:

Act 15:17 That the residue of men might seek after the Lord, and all the Gentiles, upon whom my name is called, saith the Lord, who doeth all these things.

Act 15:18 Known unto God are all his works from the beginning of the world.

In the other sense.

Act 15:27 We have sent therefore Judas and Silas, who shall also tell you the same things by mouth.

Act 15:28 For it seemed good to the Holy Ghost, and to us, to lay upon you no greater burden than these necessary things;

Act 15:29 That ye abstain from meats offered to idols, and from blood, and from things strangled, and from fornication: from which if ye keep yourselves, ye shall do well. Fare ye well.

Act 15:30 So when they were dismissed, they came to Antioch: and when they had gathered the multitude together, they delivered the epistle:

Act 15:31 Which when they had read, they rejoiced for the consolation.

Act 15:32 And Judas and Silas, being prophets also themselves, exhorted the brethren with many words, and confirmed them.

John gill writes....

And Judas and Silas being also prophets themselves,.... As well as Paul and Barnabas, and others, that were at Antioch; see Act 13:1 and by prophets are meant, not only such who had the gift of foretelling things to come; though such there were, and these might have that gift; but such who were able to explain the prophecies of the Old Testament, give the true sense of the Scriptures, and open them to the edification of others; wherefore having such gifts, they made use of them; Beza's ancient copy adds, "full of the Holy Ghost":

and exhorted the brethren with many words; which does not so much design the prolixity of their discourses, and the frequency of their ministrations, though they might preach both long and often; as the richness of the matter of them, as the Syriac version suggests, rendering it, "with a rich word"; with copiousness, fulness, and abundance of Gospel truths, with which they comforted the brethren, giving them many useful instructions and exhortations:

and confirmed them; in the doctrines of the Gospel, and particularly in their Christian liberty, and freedom from the law of Moses, in which the false teachers had endeavoured to stagger them.
