The indefinite expression may be explained from the retrospective allusion to Deu 12:24 and the purely suggestive character of the whole passage, the thing itself being supposed to be sufficiently known from the previous laws.
verses 28-30
The closing admonition is a further expansion of Deu 12:25 (see at Deu 11:21). - In Deu 12:29-31, the exhortation goes back to the beginning again, viz., to a warning against the Canaanitish idolatry (cf. Deu 12:2.). When the Lord had cut off the nations of Canaan from before the Israelites, they were to take heed that they did not get into the snare behind them, i.e., into the sin of idolatry, which had plunged the Canaanites into destruction (cf. Deu 7:16, Deu 7:25). The clause “after they be destroyed from before thee” is not mere tautology, but serves to depict the danger of the snare most vividly before their eyes. The second clause, “that thou inquire not after them” (their gods), etc., explains more fully to the Israelites the danger which threatened them. This danger was so far a pressing one, that the whole of the heathen world was animated with the conviction, that to neglect the gods of a land would be sure to bring misfortune (cf. 2Ki 17:26).
==Verse 31== Deu 12:31Deu 12:31, like Deu 12:4, with the reason assigned in Deu 12:31 : “for the Canaanites prepare (עשׂה, as in Deu 12:27) all kinds of abominations for their gods,” i.e., present offerings to these, which Jehovah hates and abhors; they even burn their children to their idols-for example, to Moloch (see at Lev 18:21).
Verse 32
The admonition to observe the whole law, without adding to it or taking from it (cf. Deu 4:2), is regarded by many commentators as the conclusion of the previous chapter. But it is more correct to understand it as an intermediate link, closing what goes before, and introductory to what follows. Strictly speaking, the warning against inclining to the idolatry of the Canaanites (Deu 12:29-31) forms a transition from the enforcement of the true mode of worshipping Jehovah to the laws relating to tempters to idolatry and worshippers of idols (ch. 13). The Israelites were to cut off not only the tempters to idolatry, but those who had been led astray to idolatry also. Three different cases are mentioned.

The first case. If a prophet, or one who had dreams, should rise up to summon to the worship of other gods, with signs and wonders which came to pass, the Israelites were not to hearken to his words, but to put him to death. The introduction of חלום חלם,
