21 The Israelites who were present in Jerusalem celebrated the Festival of Unleavened Bread for seven days with great rejoicing, while the Levites and priests praised the Lord every day with resounding instruments dedicated to the Lord.[1]

(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.

17 The Israelites who were present celebrated the Passover at that time and observed the Festival of Unleavened Bread for seven days.

Commentary on 2 Chronicles 35:1-19

(Read 2 Chronicles 35:1-19)

The destruction Josiah made of idolatry, was more largely related in the book of Kings. His solemnizing the passover is related here. The Lord's supper resembles the passover more than any other of the Jewish festivals; and the due observance of that ordinance, is a proof of growing piety and devotion. God alone can truly make our hearts holy, and prepare them for his holy services; but there are duties belonging to us, in doing which we obtain this blessing from the Lord.
