2 Kings 23:10

The king ¹  ruined Topheth in the Valley of Ben Hinnom so that no one could pass his son or his daughter through the fire to Molech. ² 

He desecrated Topheth, which was in the Valley of Ben Hinnom, so no-one could use it to sacrifice his son or daughter in the fire to Molech.

He also defiled Topheth, which is in the valley of the son of Hinnom, that no man might make his son or his daughter pass through the fire for Molech.

Then the king defiled the altar of Topheth in the valley of Ben–hinnom, so no one could ever again use it to sacrifice a son or daughter in the fire as an offering to Molech.

Then Josiah demolished the Topheth, the iron furnace griddle set up in the Valley of Ben Hinnom for sacrificing children in the fire. No longer could anyone burn son or daughter to the god Molech.

And Topheth, in the valley of the sons of Hinnom, he made unclean, so that no man might make his son or his daughter go through the fire to Molech.

He defiled Topheth, which is in the valley of Ben-hinnom, so that no one would make a son or a daughter pass through fire as an offering to Molech.

And he defiled Topheth, which is in the Valley of the Son of Hinnom, that no man might make his son or his daughter pass through the fire to Molech.
