Franz Delitzsch,
Biblical commentary the Old Testament…
“ But Josiah had turned all the place of Tophet in the valley of Benhinnom into an unclean region (2Ki 23:10) . All Jerusalem shall become an unclean place like Tophet. This is put in so many words in Jer 19:13 : The houses of Jerusalem shall become unclean like the place Tophet, namely, all houses on whose roofs idolatry has been practised. The construction of הטּמאים causes some difficulty. The position of the word at the end disfavours our connecting it with the subject בּתּי, and so does the article, which does not countenance its being taken as predicate. ”
