SEV Biblia, Chapter 23:21
Entonces mandó el rey a todo el pueblo, diciendo: Haced la pascua al SEÑOR vuestro Dios, conforme a lo que está escrito en el libro de esta alianza.
John Gill's Bible Commentary
Ver. 21. And the king commanded all the people , etc.] Not at Jerusalem only, but throughout the whole kingdom: saying, keep the passover unto the Lord your God, as it is written in this book of the covenant ; which had been lately found and read, and they had agreed to observe, and in which this ordinance was strictly enjoined, and was a commemoration of their deliverance out of Egypt, and a direction of their faith to the Messiah, the antitype of the passover.
Matthew Henry Commentary
Verses 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 ha cleared the country of the old leaven of idolatry, then they applie themselves to the keeping of the feast. There was not holden such passover in any of the foregoing reigns. The revival of 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.
