21 The people of Israel who were present at Jerusalem kept the festival of unleavened bread seven days with great gladness; and the Levites and the priests praised the Lord day by day, accompanied by loud instruments for the Lord. 22 Hezekiah spoke encouragingly to all the Levites who showed good skill in the service of the Lord. So the people ate the food of the festival for seven days, sacrificing offerings of well-being and giving thanks to the Lord the God of their ancestors. 23 Then the whole assembly agreed together to keep the festival for another seven days; so they kept it for another seven days with gladness. 24 For King Hezekiah of Judah gave the assembly a thousand bulls and seven thousand sheep for offerings, and the officials gave the assembly a thousand bulls and ten thousand sheep. The priests sanctified themselves in great numbers. 25 The whole assembly of Judah, the priests and the Levites, and the whole assembly that came out of Israel, and the resident aliens who came out of the land of Israel, and the resident aliens who lived in Judah, rejoiced. 26 There was great joy in Jerusalem, for since the time of Solomon son of King David of Israel there had been nothing like this in Jerusalem. 27 Then the priests and the Levites stood up and blessed the people, and their voice was heard; their prayer came to his holy dwelling in heaven.

Commentary on 2 Chronicles 30:21-27

(Read 2 Chronicles 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.
