Matthew Poole and continuators on Jeremiah 19:13

13 And the houses of Jerusalem, and the houses of the kings of Judah shall be defiled as the places of Tophet , because of all the houses upon whose roofs they have burnt incense unto all the host of heaven, and have poured out drink-offerings unto other Gods .

Under the Judaick Law, persons and places were defiled by touching dead bodies, or any unclean filthy thing; God threatneth in this sense to defile Tophet, as it was said before, it should be filled with dead bodies which should be buried, or lye unburied there. He sheweth that the aforementioned judgment of filling places with dead bodies, should not be restrained to Tophet in the valley of Hinnom, but reach to the dwelling houses in Hierusalem, both their Kings houses, and the meaner Subjects.

The provoking cause of which should be their Idolatry, which they had also brought into their dwelling houses, for they having flat roofs, had upon them, though not burnt children in sacrifice to Idols, yet poured out drink offerings to the Sun, Moon and Stars, and to other Idols.
