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 now commanded the people, "Celebrate the Passover to God, your God, exactly as directed in this Book of the Covenant.
22 This commanded Passover had not been celebrated since the days that the judges judged Israel - none of the kings of Israel and Judah had celebrated it.
23 But in the eighteenth year of the rule of King Josiah this very Passover was celebrated to God in Jerusalem.
24 Josiah scrubbed the place clean and trashed spirit-mediums, sorcerers, domestic gods, and carved figures - all the vast accumulation of foul and obscene relics and images on display everywhere you looked in Judah and Jerusalem. Josiah did this in obedience to the words of God's Revelation written in the book that Hilkiah the priest found in The Temple of God.
25 There was no king to compare with Josiah - neither before nor after - a king who turned in total and repentant obedience to God, heart and mind and strength, following the instructions revealed to and written by Moses. The world would never again see a king like Josiah.
