Josiah removed ... He did ... He slaughtered ... he burned

It might be best to translate so that the reader understands that other people, perhaps Hilkiah and "the priests under him" (2 Kings 23:4), might have helped Josiah do these things. (See: rc://en/ta/man/translate/figs-explicit)

he burned human bones on them

You may need to make explicit why he burned the bones. "he burned human bones on them so no one would use them again" (See: rc://en/ta/man/translate/figs-explicit)
