21 So the people of Israel who were present in Jerusalem joyously celebrated the Festival of Unleavened Bread for seven days. Each day the Levites and priests sang to the Lord, accompanied by loud instruments. 22 Hezekiah encouraged all the Levites regarding the skill they displayed as they served the Lord . The celebration continued for seven days. Peace offerings were sacrificed, and the people gave thanks to the Lord, the God of their ancestors. 23 The entire assembly then decided to continue the festival another seven days, so they celebrated joyfully for another week. 24 King Hezekiah gave the people 1,000 bulls and 7,000 sheep and goats for offerings, and the officials donated 1,000 bulls and 10,000 sheep and goats. Meanwhile, many more priests purified themselves. 25 The entire assembly of Judah rejoiced, including the priests, the Levites, all who came from the land of Israel, the foreigners who came to the festival, and all those who lived in Judah. 26 There was great joy in the city, for Jerusalem had not seen a celebration like this one since the days of Solomon, King David's son. 27 Then the priests and Levites stood and blessed the people, and God heard their prayer from 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.
