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, "Celebrate a Passover to the LORD your God following what is instructed in this scroll containing the covenant."

22 A Passover like this hadn't been celebrated since the days when the judges judged Israel; neither had it been celebrated during all the days of the Israelite and Judean kings.

23 But in the eighteenth year of King Josiah's rule, this Passover was celebrated to the LORD in Jerusalem.

24 Josiah burned those who consulted dead spirits and the mediums, the household gods and the worthless idols—all the monstrous things that were seen in the land of Judah and in Jerusalem. In this way Josiah fulfilled the words of the Instruction written in the scroll that the priest Hilkiah found in the LORD's temple.

25 There's never been a king like Josiah, whether before or after him, who turned to the LORD with all his heart, all his being, and all his strength, in agreement with everything in the Instruction from Moses.
