The details of the Passover are given by the author of Chronicles (the marginal reference). Its superiority to other Passovers seems to have consisted:

(1) in the multitudes that attended it; and

(2) in the completeness with which all the directions of the Law were observed in the celebration. Compare Nehemiah 8:17.

Surely there was not holden such a passover - Not one on purer principles, more heartily joined in by the people present, more literally consecrated, or more religiously observed. The words do not apply to the number present, but to the manner and spirit. See the particulars and mode of celebrating this passover in 2 Chronicles 35:1-18 (note).

Surely there was not holden such a passover from the days of the judges that judged Israel,.... As the king commanded; the people obeyed and kept the passover, according to the law of the Lord; the manner of its being kept is not here recorded, but is at large in 2 Chronicles 35:1 where it is observed there had not been such an one from the days of Samuel, the last of the judges; so that the days of the judges here mean the last days of them:

nor in all the days of the kings of Israel, nor of the kings of Judah; since the division of the kingdoms; for as for the kings of Israel, they kept it not; and though it was observed in the times of Hezekiah king of Judah, yet not universally, and by some in their uncleanness; for it is a mistake of Clemens of Alexandria (w), that it was not kept in the times between Samuel and Josiah; in the days of David and Solomon it might be kept by greater numbers, but not with such purity, and with such cheerfulness and joy of heart, or with so many other sacrifices attending it, or so exactly agreeable to the law of God, and with such munificence and liberality; the king, and the chief of the priests and Levites, providing out of their own substance for the people and their brethren.

Surely there was not holden {q} such a passover from the days of the judges that judged Israel, nor in all the days of the kings of Israel, nor of the kings of Judah;

(q) For the multitude and zeal of the people with the great preparation.

23:22 Such a passover - Celebrated with such solemn care, and great preparation, and numerous sacrifices, and universal joy of all good men; which was much the greater, because of their remembrance of the former wicked and miserable times under Manasseh, and Amon; and the good hopes they now had of the happy establishment of their nation, and the true religion; and of the prevention of God's judgments denounced against them. Judges - Or, from the days of Samuel, the last of the judges; as it is expressed 2Chron 35:18. None of the kings had taken such care to prepare themselves, the priests, and people, and accurately to observe all the rites, and diligently to purge out all uncleanness, and to renew their covenant with God. And undoubtedly God was pleased to recompense their zeal in destroying idolatry with uncommon tokens of his presence and favour. All this concurred to make it such a passover as had not been, even in the days of Hezekiah.

23:15-24 Josiah's zeal extended to the cities of Israel within his reach. He carefully preserved the sepulchre of that man of God, who came from Judah to foretell the throwing down of Jeroboam's altar. When they had cleared the country of the old leaven of idolatry, then they applied themselves to the keeping of the feast. There was not holden such a passover in any of the foregoing reigns. The revival of a long-neglected ordinance, filled them with holy joy; and God recompensed their zeal in destroying idolatry with uncommon tokens of his presence and favour. We have reason to think that during the remainder of Josiah's reign, religion flourished.
