(25) And all the congregation.—Three classes of persons took part in the festival—(1) the Judseans, including the priests and Levites; (2) their Israelite guests; (3) the “strangers”—gêrîm—i.e., the proselytes, both those who came from the northern kingdom arid those who dwelt in Judah. The word gêrîm is not the same as gârîm (2Chronicles 15:9), with which Lange’s comment confuses it. (Comp. Leviticus 17:12.)

30:21-27 Many prayers were put up to God with the peace-offerings. In these Israel looked to God as the God of their fathers, a God in covenant with them. There was also abundance of good preaching. The Levites read and explained the Scriptures. Faith cometh by hearing, and true religion preaching has abounded. They sang psalms every day: praising God should be much of our work in religious assemblies. Having kept the seven days of the feast in this religious manner, they had so much comfort in it, that they kept other seven days also. This they did with gladness. Holy duties should be done with holy gladness. And when sinners humble themselves before the Lord, they may expect gladness in his ordinances. Those who taste this happiness will not soon grow weary of it, but will be glad to prolong their enjoyment.The strangers - See the 2 Chronicles 15:9 note. 24. and a great number of priests sanctified themselves—so that there would be a sufficient number of hands for the additional services.

And all the congregation of Judah, with the priests and Levites,.... The people that were gathered together out of the several cities of Judah, which no doubt was the largest congregation, with whom the priests and Levites are joined, as being of that kingdom, and dwellers in Jerusalem, where their office lay:

and all the congregation that came out of Israel; out of the ten tribes, particularly Ephraim, Manasseh, Issachar, and Zebulun, 2 Chronicles 30:18, and the strangers that came out of the land of Israel, and that dwelt in Judah, rejoiced; the proselytes, even such as were circumcised, who ate of the passover, and kept the feast of unleavened bread, as well as the other days of rejoicing, the former of which none might partake of but circumcised persons; and it can hardly be thought that any other would come out of Israel on such an occasion, see Exodus 12:48.

And all the congregation of Judah, with the priests and the Levites, and all the congregation that came out of Israel, and the strangers that came out of the land of Israel, and that dwelt in Judah, rejoiced.
