(25) The land itself vomiteth out her inhabitants.—From the creation the earth shared in the punishment of man’s guilt (Genesis 3:17), and at the restitution of all things she is to participate in his restoration (Romans 8:19-22). The physical condition of the land, therefore, depends upon the moral conduct of man. When he disobeys God’s commandments she is parched up and does not yield her fruit” (Deuteronomy 11:17). “The land is defiled” when he defiles himself. When he walks in the way of the Divine commands she is blessed (Leviticus 25:19; Leviticus 26:4); “God is merciful unto his land and to his people” (Deuteronomy 32:43). Hence, “the earth mourneth” when her inhabitants sin (Isaiah 24:4-5), and “the earth is glad” when God avenges the cause of His people (Psalm 96:11-13). It is owing to this intimate connection between them that the land, which is here personified, is represented as loathing the wicked conduct of her children and being unable to restrain them. She nauseated them. The same figure is used in Leviticus 18:28; Leviticus 20:22; and in Revelation 3:16.

18:1-30 Unlawful marriages and fleshly lusts. - Here is a law against all conformity to the corrupt usages of the heathen. Also laws against incest, against brutal lusts, and barbarous idolatries; and the enforcement of these laws from the ruin of the Canaanites. God here gives moral precepts. Close and constant adherence to God's ordinances is the most effectual preservative from gross sin. The grace of God only will secure us; that grace is to be expected only in the use of the means of grace. Nor does He ever leave any to their hearts' lusts, till they have left him and his services.The land designed and consecrated for His people by Yahweh Leviticus 25:23 is here impersonated, and represented as vomiting forth its present inhabitants, in consequence of their indulgence in the abominations that have been mentioned. The iniquity of the Canaanites was now full. See Genesis 15:16; compare Isaiah 24:1-6. The Israelites in this place, and throughout the chapter, are exhorted to a pure and holy life, on the ground that Yahweh, the Holy One, is their God and that they are His people. Compare Leviticus 19:2. It is upon this high sanction that they are peremptorily forbidden to defile themselves with the pollutions of the pagan. The only punishment here pronounced upon individual transgressors is, that they shall "bear their iniquity" and be "cut off from among their people." We must understand this latter phrase as expressing an "ipso facto" excommunication or outlawry, the divine Law pronouncing on the offender an immediate forfeiture of the privileges which belonged to him as one of the people in covenant with Yahweh. See Exodus 31:14 note. The course which the Law here takes seems to be first to appeal to the conscience of the individual man on the ground of his relation to Yahweh, and then Leviticus 20 to enact such penalties as the order of the state required, and as represented the collective conscience of the nation put into operation. 25. therefore I do visit the iniquity thereof upon it; and the land itself vomiteth out her inhabitants—The Canaanites, as enormous and incorrigible sinners, were to be exterminated; and this extermination was manifestly a judicial punishment inflicted by a ruler whose laws had been grossly and perseveringly outraged. But before a law can be disobeyed, it must have been previously in existence; and hence a law, prohibiting all the horrid crimes enumerated above—a law obligatory upon the Canaanites as well as other nations—was already known and in force before the Levitical law of incest was promulgated. Some general Iaw, then, prohibiting these crimes must have been published to mankind at a very early period of the world's history; and that law must either have been the moral law, originally written on the human heart, or a law on the institution of marriage revealed to Adam and known to the Canaanites and others by tradition or otherwise. I do visit; I am now visiting, or about to visit, i. e. to punish. See Isaiah 26:21.

The land itself vomiteth out her inhabitants, as no less burdens to the earth than corrupted food is to the stomach. See Jeremiah 9:19 Micah 2:10.

And the land is defiled,.... The inhabitants of it, with the immoralities and idolatries before mentioned:

therefore I do visit the iniquity thereof upon it; or punish the inhabitants that are on it for their sins:

and the land itself vomiteth out her inhabitants; as a stomach loaded with corrupt and bad food it has taken in, nauseates it, and cannot bear and retain it, but casts it up, and never receives it again; so the land of Canaan is represented as loathing its inhabitants, and as having an aversion to them, and indignation against them, and as not being able to bear them, but entirely willing to be rid of them and throw them out of their places in it, never to be admitted more, being as nauseous and as useless as the cast of a man's stomach; see Revelation 3:16.

And the land is defiled: therefore I do {m} visit the iniquity thereof upon it, and the land itself {n} vomiteth out her inhabitants.

(m) I will punish the land where such incestuous marriages and pollutions are tolerated.

(n) He compares the wicked to evil humours and overeating, which corrupt the stomach, and oppress nature, and therefore must be cast out by vomit.
