2 Kings 23
13The king also desecrated the high places east of Jerusalem, to the south of the Mount of Corruption, which King Solomon of Israel had built for Ashtoreth the abomination of the Sidonians, for Chemosh the abomination of the Moabites, and for Milcome the abomination of the Ammonites. 14He smashed the sacred pillars to pieces, cut down the Asherah poles, and covered the sites with human bones.
19Just as Josiah had done at Bethel, so also in the cities of Samaria he removed all the shrines of the high places set up by the kings of Israel who had provoked the LORD to anger. 20On the altars he slaughtered all the priests of the high places, and he burned human bones on them. Then he returned to Jerusalem.
What is the significance of these human bones?
