Thou shalt not bow down to their gods, nor serve them, nor do after their works. It is always to be borne in mind that with the idolatries of the heathen were connected "works of darkness," which it is shameful even to speak of.
The rites of Baal and Ashtoreth, of Chemosh, Molech, Rimmon, and the other Canaanite and Syrian deities were at once defiled by the abomination of human sacrifices, and polluted with the still more debasing evil of religious impurity.
"The sacrifice offered to Ashtoreth," says Dr. Dollinger, "consisted in the prostitution of women: the women submitted themselves to the visitors of the feast, in the temple of the goddess or the adjoining precinct.
A legend told of Astarte (Ashtoreth) having prostituted herself in Tyre for ten years: and in many places matrons, as well as maidens, consecrated themselves for a length of time, or on the festivals of the goddess, with a view of propitiating her, or earning her favour as hieroduli of unchastity … In this way they went so far at last as to contemplate the abominations of unnatural lust as a homage rendered to the deity, and to exalt it into a regular cultus.
The worship of the goddess at Aphaca in Lebanon was specially notorious in this respect. The temple in a solitary situation was, as Eusebius tells us, a place of evil-doing for such as chose to ruin their bodies in scandalous ways … Criminal intercourse with women, impurity, shameful and degrading deeds, were practised in the temple, where there was no custom and no law, and no honourable or decent human being could be found."
Thou shalt utterly overthrow them. The heathen gods are identified with their images. These were to be torn from their bases, overthrown, and rolled in the dust for greater contempt and ignominy. They were then to be broken up and burnt, till the gold and the silver with which they were overlaid was calcined and could be stamped to powder.
Nothing was to be spared that had been degraded by idolatry, either for its beauty or its elaborate workmanship, or its value. All was hateful to God, and was to be destroyed.
