2 Kings 23:6, 12, 15

He took the Asherah pole from the temple of the LORD to the Kidron Valley outside Jerusalem and burned it there. He ground it to powder and scattered the dust over the graves of the common people.

He pulled down the altars the kings of Judah had erected on the roof near the upper room of Ahaz, and the altars Manasseh had built in the two courts of the temple of the LORD. He removed them from there, smashed them to pieces and threw the rubble into the Kidron Valley.

Even the altar at Bethel, the high place made by Jeroboam son of Nebat, who had caused Israel to sin—even that altar and high place he demolished. He burned the high place and ground it to powder, and burned the Asherah pole also.
