2 Kings 23:19-23

Josiah also destroyed all the temples at the high places in the cities of Samaria. The kings of Israel had built those temples, which had made the Lord very angry. Josiah destroyed them, just as he had destroyed the place of worship at Bethel.

Josiah killed all the priests of the high places that were in Samaria. He killed the priests on those altars and burned men’s bones on the altars so that they could never be used again. Then he went back to Jerusalem.

Then King Josiah gave a command to all the people. He said, “Celebrate the Passover for the Lord your God. Do this just as it is written in the Book of the Agreement.”

The people had not celebrated a Passover like this since the days when the judges ruled Israel. None of the kings of Israel or the kings of Judah ever had such a big celebration for Passover.

They celebrated this Passover for the Lord in Jerusalem during Josiah’s 18th year as king.
