Jamieson, Fausset and Brown on 2 Chronicles 30:10-12

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.
