13 So a very great number of people came together at Jerusalem to keep the feast of unleavened bread in the second month. 14 And they got to work and took away all the altars in Jerusalem, and they put all the vessels for burning perfumes into the stream Kidron. 15 Then on the fourteenth day of the second month they put the Passover lambs to death: and the priests and the Levites were shamed, and made themselves holy and took burned offerings into the house of the Lord. 16 And they took their places in their right order, as it was ordered in the law of Moses, the man of God: the priests draining out on the altar the blood given them by the Levites. 17 For there were still a number of the people there who had not made themselves holy: so the Levites had to put Passover lambs to death for those who were not clean, to make them holy to the Lord. 18 For a great number of the people from Ephraim and Manasseh, Issachar and Zebulun, had not made themselves clean, but they took the Passover meal, though not in the right way. For Hezekiah had made prayer for them, saying, May the good Lord have mercy on everyone 19 Who, with all his heart, is turned to God the Lord, the God of his fathers, even if he has not been made clean after the rules of the holy place. 20 And the Lord gave ear to Hezekiah, and made the people well.

21 So the children of Israel who were present in Jerusalem kept the feast of unleavened bread for seven days with great joy: and the Levites and the priests gave praise to the Lord day by day, making melody to the Lord with loud instruments. 22 And Hezekiah said kind words to the Levites who were expert in the ordering of the worship of the Lord: so they kept the feast for seven days, offering peace-offerings and praising the Lord, the God of their fathers. 23 And by the desire of all the people, the feast went on for another seven days, and they kept the seven days with joy. 24 For Hezekiah, king of Judah, gave to the people for offerings, a thousand oxen and seven thousand sheep; and the rulers gave a thousand oxen and ten thousand sheep; and a great number of priests made themselves holy. 25 And all the people of Judah, with the priests and the Levites, and those who had come from Israel, and men from other lands who had come from Israel or who were living in Judah, were glad with great joy. 26 So there was great joy in Jerusalem: for nothing like this had been seen in Jerusalem from the time of Solomon, the son of David, king of Israel. 27 Then the priests and the Levites gave the people a blessing: and the voice of their prayer went up to the holy place of God 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.
