Congregation Broken Up

Paul in his travels, preached the gospel first to the Jews, the people of G-d, offering them pardon through their own Messiah; and, when they rejected it, turned to the Gentiles.
[Acts 13:42] And when the Jews were gone out of the synagogue, the Gentiles besought that these words might be preached to them the next sabbath.
And when the Jews - There is a great variety in the Mss. on this verse; and in the ancient versions, "And when they were gone out, they besought them that these words might be spoken," The Syriac reads it, "When they departed from them, they sought from them that these words might be spoken to them on another Sabbath." The Arabic, "Some of the synagogue of the Jews asked of them that they would exhort the Gentiles with them," etc. If these readings be correct, then the meaning is that some of the Jews exhorted the apostles to proclaim these truths at some other time; particularly to the Gentiles. The MSS. greatly vary in regard to the passage, and it is perhaps impossible to determine the true reading. If the present reading in the English translation is to be regarded as genuine--of which, however, there is very little evidence--the meaning is, that a part of the Jews, perhaps a majority of them, rejected the message, and went out, though many of them followed Paul and Barnabas.
The Gentiles besought - The expression is that Paul besought the Gentiles.
The next Sabbath - The margin has probably the correct rendering of the passage. The meaning of the verse is that a wish was expressed that these doctrines might be repeated to them in the intermediate time before the next Sabbath.
[43] Now when the congregation was broken up, many of the Jews and religious proselytes followed Paul and Barnabas: who, speaking to them, persuaded them to continue in the grace of God.
There were some of the Jews that were so incensed against the preaching of the gospel, not to the Gentiles, but to themselves, that they would not bear to hear it, but went out of the Synagogue while Paul was preaching, in contempt of him and his doctrine, and to the disturbance of the congregation. They went out of the Synagogue, not only to show that they did not believe the gospel, but because they were resolved they would not, and therefore got out of the hearing of those things that had a tendency to convince them.
The Gentiles were as willing to hear the gospel that they begged:
1. That the same offer might be made to them that was made to the Jews. Paul in this sermon had brought the word of salvation to the Jews and proselytes, but had taken no notice of the Gentiles; and therefore they begged that forgiveness of sins through the Messiah might be preached to them, as it was to the Jews.
2. That the same instructions might be given to them. They had heard the doctrine of Messiah, but did not understand it at the first hearing, nor could they remember all that they had heard, and therefore they begged it might be preached to them again.
There were some, nay, there were many, both of Jews and proselytes, that were wrought upon by the preaching of the gospel. Those who aggravated the matter of the Jews' rejection by the preaching of the gospel, cried out, as is usual in such cases, "They have cast away, and cast off, all the people of G-d." "Nay," says Paul, "it is not so; for abundance of the Jews have embraced the Messiah, and are taken in;" himself for one, Romans 11:1, 5. So it was here: Many of the Jews and religious proselytes followed Paul and Barnabas, and received further instructions and encouragement from them:
1. They submitted to the grace of G-d, and were admitted to the benefit and comfort of it, which is implied in their being exhorted to continue in it. They followed Paul and Barnabas; they became their disciples, or rather the students of the Messiah, whose agents they were. Those that join themselves to Messiah will join themselves to his ministers, and follow them. And Paul and Barnabas, though they were sent to the Gentiles, yet bade those of the Jews welcome that were willing to come under their instructions, such hearty well-wishers were they to all the Jews and their friends, if they pleased.
2. They were exhorted and encouraged to persevere herein: Paul and Barnabas, speaking to them with all the freedom and friendship imaginable, persuaded them to continue in the grace of G-d, to hold fast that which they had received, to continue in their belief of the gospel of grace, their dependence upon the Spirit of grace, and their attendance upon the means of grace. And the grace of G-d shall not be wanting to those who thus continue in it, but they remained them G-d is a just G-d and they are accountable for their actions.
The word judge here does not mean they expressed such an opinion, by their conduct they condemned themselves. Sinners by their conduct do in fact condemn themselves, and show that they are not only unfit to be saved, but that they have advanced so far in wickedness that there is no hope of their salvation, and no propriety in offering them, any farther, eternal life.
Paul choose to turn to the Gentiles, himself.
[47] For so hath the Lord commanded us, saying, I have set thee to be a light of the Gentiles, that thou shouldest be for salvation unto the ends of the earth.
For so - Paul, as usual, appeals to the Scriptures in order to justify his course. He here appeals to the Old Testament, rather than to the command of the Savior, because the Jews recognized the authority of their own Scriptures, while they would have turned in scorn from the command of Y’Shua of Nazareth.
I have set thee - This passage is found in Isaiah 49:6. That it refers to the Messiah there can be no doubt. From the fortieth chapter of Isaiah to the end of the prophecies, Isaiah had a primary and main reference to the times of the Messiah.
Of the Gentiles - This was in accordance with the uniform doctrines of Isaiah, Isaiah 42:1; 44:3; 60:3, 5, 16; 61:6, 9; 62:2; 66:12. Comp. Romans 15:9-12.
For salvation - To save sinners. Unto the ends of the earth, to all lands; in all nations
[48] And when the Gentiles heard this, they were glad, and glorified the word of the Lord: and as many as were ordained to eternal life believed.
When the Gentiles heard this - Heard that the gospel was to be preached to them. for the purpose of salvation.
They glorified the word of the L-rd - They honored it as a message from G-d; they recognized and received it as the word of G-d. The expression conveys the idea of praise on account of it, and of reverence for the message as the word of G-d.
And as many as were ordained - it refers to the doctrine of election-- to G-d's ordaining men to eternal. They were then inclined by an influence from without themselves, or so disposed as to embrace eternal life. It refers not to an eternal decree, but that then there was such an influence as to dispose them, or incline them, to lay hold on salvation. This implies the doctrine of election. It was in fact that doctrine expressed. It was nothing but G-d's disposing them to embrace eternal life. And that He does this according to a plan in His own mind--a plan which is unchangeable as G-d Himself is unchangeable--is clear from the Scriptures.
[49] And the word of the Lord was published throughout all the region.
The split is not complete yet between the Messianic and Christianity.
