He removed the Asherah pole from the Lord’s temple and took it outside Jerusalem to the Kidron Valley, where he burned it. ¹  He smashed it to dust and then threw the dust in the public graveyard. ² 

Jehoahaz had no army left ¹  except for fifty horsemen, ten chariots, and 10,000 foot soldiers. The king of Syria had destroyed his troops ²  and trampled on them like dust. ³ 

The king tore down the altars the kings of Judah had set up on the roof of Ahaz’s upper room, as well as the altars Manasseh had set up in the two courtyards of the Lord’s temple. He crushed them up ¹  and threw the dust in the Kidron Valley.

He also tore down the altar in Bethel ¹  at the high place made by Jeroboam son of Nebat, who encouraged Israel to sin. ²  He burned all the combustible items at that high place and crushed them to dust; including the Asherah pole. ³ 

The king ordered Hilkiah the high priest, the high-ranking priests, ¹  and the guards ²  to bring out of the Lord’s temple all the items that were used in the worship of ³  Baal, Asherah, and all the stars of the sky. ⁴  The king ⁵  burned them outside of Jerusalem in the terraces ⁶  of Kidron, and carried their ashes to Bethel. ⁷
