2 Kings 23:23 Meaning and Commentary

2 Kings 23:23

But in the eighteenth year of king Josiah, wherein this
passover was holden to the Lord in Jerusalem.
] This shows that Josiah must begin the reformation very early that year, since he did all that is before recorded in this and the preceding chapter by the fourteenth of Nisan, the day on which the passover was kept, which month answers to part of our March and part of April, see ( 2 Kings 22:3 ) and was the same year the repairs of the temple were finished.

2 Kings 23:23 In-Context

21 The king commanded all the people, "Keep the Passover of the Lord your God as written in the book of the covenant."
22 No such Passover had ever been kept from the time of the judges who judged Israel through the entire time of the kings of Israel and Judah.
23 But in the eighteenth year of King Josiah, this Passover was observed to the Lord in Jerusalem.
24 In addition, Josiah removed the mediums, the spiritists, household idols, images, and all the detestable things that were seen in the land of Judah and in Jerusalem. He did this in order to carry out the words of the law that were written in the book that Hilkiah the priest found in the Lord's temple.
25 Before him there was no king like him who turned to the Lord with all his mind and with all his heart and with all his strength according to all the law of Moses, and no one like him arose after him.
