13 So a huge crowd assembled at Jerusalem in midspring to celebrate the Festival of Unleavened Bread. 14 They set to work and removed the pagan altars from Jerusalem. They took away all the incense altars and threw them into the Kidron Valley. 15 On the fourteenth day of the second month, one month later than usual, the people slaughtered the Passover lamb. This shamed the priests and Levites, so they purified themselves and brought burnt offerings to the Temple of the Lord . 16 Then they took their places at the Temple as prescribed in the Law of Moses, the man of God. The Levites brought the sacrificial blood to the priests, who then sprinkled it on the altar. 17 Since many of the people had not purified themselves, the Levites had to slaughter their Passover lamb for them, to set them apart for the Lord . 18 Most of those who came from Ephraim, Manasseh, Issachar, and Zebulun had not purified themselves. But King Hezekiah prayed for them, and they were allowed to eat the Passover meal anyway, even though this was contrary to the requirements of the Law. For Hezekiah said, "May the Lord, who is good, pardon those 19 who decide to follow the Lord, the God of their ancestors, even though they are not properly cleansed for the ceremony." 20 And the Lord listened to Hezekiah's prayer and healed the people.

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 30:13-20

(Read 2 Chronicles 30:13-20)

The great thing needful in attendance upon God in solemn ordinances, is, that we make heart-work of it; all is nothing without this. Where this sincerity and fixedness of heart are, there may yet be many things short of the purification of the sanctuary. These defects need pardoning, healing grace; for omissions in duty are sins, as well as omissions of duty. If God should deal with us in strict justice, even as to the very best of our doings, we should be undone. The way to obtain pardon, is to seek it of God by prayer; it must be gotten by petition through the blood of Christ. Yet every defect is sin, and needs forgiveness; and should be matter to humble, but not to discourage us, though nothing can make up for the want of a heart prepared to seek the Lord.

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.
