Второзаконие 17:5

Not only did the inclination to nature-worship, such as the setting up of the idols of Ashera and Baal, belong to the crimes which merited punishment, but also a manifest transgression of the laws concerning the worship of Jehovah, such as the offering of an ox or sheep that had some fault, which was an abomination in the sight of Jehovah (see at Lev 22:20.). "Any evil thing," i.e., any of the faults enumerated in Lev 22:22-24.

The charge of this chapter is, I. Concerning the purity and perfection of all those animals that were offered in sacrifice (Deu 17:1). II. Concerning the punishment of those that worshipped idols (Deu 17:2-7). III. Concerning appeals from the inferior courts to the great sanhedrim (Deu 17:8-13). IV. Concerning the choice and duty of a king (Deu 17:14, etc.).

17:5 the gates: A typical town in ancient Israel was small (about 10 acres or less) and crowded. It had few open areas except for a plaza just inside or outside the main gate where public meetings were held, including trials and other judicial proceedings. The place here is clearly outside of the town because stoning to death would not occur inside the walls (22:24; 1 Kgs 21:10) except under unusual circumstances (Deut 22:21).
