2 Kings 23:19-21
19 Josiah tore down all the temples of the high places built by Israel’s kings in the Samaritan cities. These high places had caused the Eternal’s anger to boil. Josiah did the same thing to these houses as he did to the houses in Bethel.
20 Josiah also killed all the priests who were present at the high places. He killed them on the altars and set fire to their bones. Then he went back to the place from which he came—Jerusalem.
Josiah (to the people): 21 The covenant book that was found in the temple says we must observe the Passover and rejoice in the Eternal One our God, who led us out of bondage in Egypt.
