Ye shall therefore keep all my statutes He now warns the Israelites, for the third time, not to imitate the Gentiles, and exhorts them to keep themselves within the limits of the Law. I have already pointed out that this was not done without reason, since otherwise they might have easily fallen away into the approval of their evil habits. Moreover, lest they should shake off God's yoke, after He has said that the nations of Canaan were destroyed on account of similar abominations, He adds, that they were made the inheritors of the land on condition that they should separate themselves from heathen nations.

The ground is here again stated on which all these laws of holiness should be obeyed. See Leviticus 18:24-30 note.

The land, whither I bring you to dwell therein, spue you not out - See this energetic prosopopoeia explained in the note on Leviticus 18:25 (note). From this we learn that the cup of the iniquities of the Canaanitish nations was full; and that, consistently with Divine justice, they could be no longer spared.

Ye shall therefore keep all my statutes,.... All the ordinances, institutions, and appointments of God, whether observed in this chapter or elsewhere, but particularly those concerning incestuous marriages and unlawful copulations:
and all my judgments, and do them; all the laws and commandments of God, founded injustice and judgment, and according to the rules thereof; or else, as Aben Ezra, the judgments of punishment, or the penalties annexed to the above laws, which were carefully to be observed, and put into execution, to deter from the transgression of them:
that the land, whither I bring you to dwell therein, spew you not out; as the stomach does its food when it is loathsome and nauseous to it, and it cannot bear it; see Leviticus 18:25.

The list of punishments concludes, like the prohibitions in Leviticus 18:24., with exhortations to observe the commandments and judgments of the Lord, and to avoid such abominations (on Leviticus 18:22 cf. Leviticus 18:3-5, Leviticus 18:26, Leviticus 18:28, Leviticus 18:30; and on Leviticus 18:23 cf. Leviticus 18:3 and Leviticus 18:24). The reason assigned for the exhortations is, that Jehovah was about to give them for a possession the fruitful land, whose inhabitants He had driven out because of their abominations, and that Jehovah was their God, who had separated Israel from the nations. For this reason (Leviticus 18:25) they were also to sever (make distinctions) between clean and unclean cattle and birds, and not make their souls (i.e., their persons) abominable through unclean animals, with which the earth swarmed, and which God had "separated to make unclean," i.e., had prohibited them from eating or touching when dead, because they defiled (see ch. 11). For (Leviticus 18:26) they were to be holy, because Jehovah their God was holy, who had severed them from the nations, to belong to Him, i.e., to be the nation of His possession (see Exodus 19:4-6).
