21 And the children of Israel, that were present at Jerusalem, held the feast of unleavened bread seven days with great gladness; and the Levites and the priests praised Jehovah day by day, with the instruments of praise to Jehovah. 22 And Hezekiah spoke consolingly to all the Levites that had understanding in the good knowledge of Jehovah; and they ate the feast-offerings the seven days, sacrificing peace-offerings, and extolling Jehovah the God of their fathers. 23 And the whole congregation took counsel to observe other seven days; and they observed the seven days with gladness. 24 For Hezekiah king of Judah gave to the congregation as heave-offering: a thousand bullocks and seven thousand sheep; and the princes gave to the congregation a thousand bullocks and ten thousand sheep; and a great number of priests hallowed themselves. 25 And the whole 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. 26 And there was great joy in Jerusalem; for since the time of Solomon the son of David, king of Israel, there had not been the like in Jerusalem. 27 And the priests the Levites arose and blessed the people; and their voice was heard, and their prayer came up to his holy habitation, to the heavens.

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.
