21 And the children of Israel that were present at Jerusalem kept the feast of unleavened bread seven days with great gladness; and the Levites and the priests praised Jehovah day by day, [singing] with loud instruments unto Jehovah. 22 And Hezekiah spake comfortably unto all the Levites that had good understanding [in the service] of Jehovah. So they did eat throughout the feast for the seven days, offering sacrifices of peace-offerings, and making confession to Jehovah, the God of their fathers. 23 And the whole assembly took counsel to keep other seven days; and they kept [other] seven days with gladness. 24 For Hezekiah king of Judah did give to the assembly for offerings a thousand bullocks and seven thousand sheep; and the princes gave to the assembly a thousand bullocks and ten thousand sheep: and a great number of priests sanctified themselves. 25 And all the assembly of Judah, with the priests and the Levites, and all the assembly that came out of Israel, and the sojourners that came out of the land of Israel, and that dwelt in Judah, rejoiced. 26 So there was great joy in Jerusalem; for since the time of Solomon the son of David king of Israel there was not the like in Jerusalem. 27 Then the priests the Levites arose and blessed the people: and their voice was heard, and their prayer came up to his holy habitation, even unto 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.
