2 Kings 23:19-21 New English Translation (NET Bible)
19 Josiah also removed all the shrines on the high places in the cities of Samaria. The kings of Israel had made them and angered the Lord. He did to them what he had done to the high place in Bethel. 20 He sacrificed all the priests of the high places on the altars located there, and burned human bones on them. Then he returned to Jerusalem.
21 The king ordered all the people, “Observe the Passover of the Lord your God, as prescribed in this scroll of the covenant.”
