2 Chronicles 11:12-13
13-17. the priests and the Levites . . . resorted to him out of all their coasts—This was an accession of moral power, for the maintenance of the true religion is the best support and safeguard of any nation; and as it was peculiarly the grand source of the strength and prosperity of the Hebrew monarchy, the great numbers of good and pious people who sought an asylum within the territories of Judah contributed greatly to consolidate the throne of Rehoboam. The cause of so extensive an emigration from the kingdom of Israel was the deep and daring policy of Jeroboam, who set himself to break the national unity by entirely abolishing, within his dominions, the religious institutions of Judaism. He dreaded an eventual reunion of the tribes if the people continued to repair thrice a year to worship in Jerusalem as they were obliged by law to do. Accordingly, on pretense that the distance of that city was too great for multitudes of his subjects, he fixed upon two more convenient places, where he established a new mode of worshipping God under gross and prohibited symbols [1Ki 12:26-33]. The priests and Levites, refusing to take part in the idolatrous ceremonies, were ejected from their living [2Ch 11:13, 14]. Along with them a large body of the people who faithfully adhered to the instituted worship of God, offended and shocked by the impious innovations, departed from the kingdom.
2 Chronicles 11:16
2 Chronicles 15:9
9-15. he gathered all Judah and Benjamin—Not satisfied with these minor measures of purification and improvement, Asa meditated a grand scheme which was to pledge his whole kingdom to complete the work of reformation, and with this in view he waited for a general assembly of the people.
and the strangers with them out of Ephraim and Manasseh—The population of Asa's kingdom had been vastly increased by the continued influx of strangers, who, prompted by motives either of interest or of piety, sought in his dominions that security and freedom which they could not enjoy amid the complicated troubles which distracted Israel. and out of Simeon—Although a portion of that tribe, located within the territory of Judah, were already subjects of the southern kingdom, the general body of the Simeonites had joined in forming the northern kingdom of Israel. But many of them now returned of their own accord.2 Chronicles 30:11
10-12. the posts passed from city to city—It is not surprising that after so long a discontinuance of the sacred festival, this attempt to revive it should, in some quarters, have excited ridicule and opposition. Accordingly, among the tribes of Ephraim, Manasseh, and Zebulun, Hezekiah's messengers met with open insults and ill usage. Many, however, in these very districts, as well as throughout the kingdom of the ten tribes, generally complied with the invitation; while, in the kingdom of Judah, there was one unanimous feeling of high expectation and pious delight. The concourse that repaired to Jerusalem on the occasion was very great, and the occasion was ever after regarded as one of the greatest passovers that had ever been celebrated.
2Ch 30:13-27. THE ASSEMBLY DESTROYS THE ALTARS OF IDOLATRY.
2 Chronicles 30:18
16-18. the priests sprinkled the blood, which they received of the hand of the Levites—This was a deviation from the established rules and practices in presenting the offerings of the temple. The reason was, that many present on the occasion having not sanctified themselves, the Levites slaughtered the paschal victims (see on 2Ch 35:5) for everyone that was unclean. At other times the heads of families killed the lambs themselves, the priests receiving the blood from their hands and presenting it on the altar. Multitudes of the Israelites, especially from certain tribes (2Ch 30:18), were in this unsanctified state, and yet they ate the passover—an exceptional feature and one opposed to the law (Nu 9:6); but this exception was allowed in answer to Hezekiah's prayer (2Ch 30:18-20).
