2 Chronicles 30:12-27 New Revised Standard Version (NRSV)
12 The hand of God was also on Judah to give them one heart to do what the king and the officials commanded by the word of the Lord.
13 Many people came together in Jerusalem to keep the festival of unleavened bread in the second month, a very large assembly. 14 They set to work and removed the altars that were in Jerusalem, and all the altars for offering incense they took away and threw into the Wadi Kidron. 15 They slaughtered the passover lamb on the fourteenth day of the second month. The priests and the Levites were ashamed, and they sanctified themselves and brought burnt offerings into the house of the Lord. 16 They took their accustomed posts according to the law of Moses the man of God; the priests dashed the blood that they received[a] from the hands of the Levites. 17 For there were many in the assembly who had not sanctified themselves; therefore the Levites had to slaughter the passover lamb for everyone who was not clean, to make it holy to the Lord. 18 For a multitude of the people, many of them from Ephraim, Manasseh, Issachar, and Zebulun, had not cleansed themselves, yet they ate the passover otherwise than as prescribed. But Hezekiah prayed for them, saying, “The good Lord pardon all 19 who set their hearts to seek God, the Lord the God of their ancestors, even though not in accordance with the sanctuary’s rules of cleanness.” 20 The Lord heard Hezekiah, and healed the people. 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.
