Having thus set forth the law which was to crown and complete the long resistance of faithful Israel to idolatry, our author goes on to prohibit and to decree punishment for any action likely to lead to the worship of false gods. He absolutely forbids any inquiry into the religions of the Canaanites. "Take heed to thyself that thou inquire not after their gods, saying, How do these nations serve their gods? even so will I do likewise." All that was acceptable to Yahweh was included in the law of Israel, and beyond that they were on no account to go in their worship. "What thing soever I command you, that shall ye observe to do: thou shalt not add thereto nor diminish from it." But it should be observed that the inquiry here forbidden has nothing in common with the scientific inquiries of Comparative Religion in our time. Curiosity of that kind, supported by the motive of discovering how religion had grown, was unknown at that early age of the world, probably everywhere, certainly in Israel. The only curiosity powerful enough to result in action then was that which tried to learn how the ritual might be made more potent in its influence over Yahweh by gathering attractive features from every known religion. That was one of the distinguishing characteristics of Manasseh's reign. The Canaanite religions, the religions of Egypt and Assyria, were all laid under contribution; and wherever there was a feature which promised additional power with God or the gods, that was eagerly adopted. Israel had lost faith in Yahweh, owing to the successes of Assyria. In unbelieving terror men were wildly grasping at any means of safety. They worshipped Yahweh, lest He should do them harm, but they joined with Him the gods of their foes, to secure if possible their favour also. Inquiry into other religions, with the intent of adopting something from them which would make either Yahweh or the strange gods, or both, propitious to them, was rife. Like the heathen population who had been transported by Assyria into the territory of the ten tribes, men "feared Yahweh, and served their graven images." All that is here sternly condemned, and Judah is taught to look only to the Divine commands for effective means of approach to their God. The prohibition, therefore, does not import mere fanatical opposition to knowledge. It is a necessary practical measure of defence against idolatry; and only those can disapprove of it who are incapable of estimating the value which the true religion in its Old Testament shape had and has for the world. To preserve that was the high and unique calling of Israel. Any narrowness, real or supposed, which this great task imposed upon that people, is amply compensated for by their guardianship of the spiritual life of mankind.
