With mankind - This abominable crime, frequent among the Greeks and Romans as well as the Canaanites, may be punished with death in this country.

Thou shall not lie with mankind as with womankind,.... By carnal knowledge of them, and carnal copulation with them, and mixing bodies in like manner: this is the sin commonly called sodomy, from the inhabitants of Sodom, greatly addicted to it, for which their city was destroyed by fire: those that are guilty of this sin, are, by the apostle, called "abusers of themselves with mankind", 1 Corinthians 6:9,

it is abomination; it is so to God, as the above instance of his vengeance shows, and ought to be abominable to men, as being not only contrary to the law of God, but even contrary to nature itself, and what is never to be observed among brute creatures.

Lastly, it was forbidden to "lie with mankind as with womankind," i.e., to commit the crime of paederastia, that sin of Sodom (Genesis 19:5), to which the whole of the heathen were more or less addicted (Romans 1:27), and from which even the Israelites did not keep themselves free (Judges 19:22.); or to "lie with any beast." "Into no beast shalt thou give thine emission of seed,...and a woman shall not place herself before a beast to lie down thereto." רבע equals רבץ "to lie," is the term used particularly to denote a crime of this description (Leviticus 20:13 and Leviticus 20:15, Leviticus 20:16, cf. Exodus 22:18). Lying with animals was connected in Egypt with the worship of the goat; at Mendes especially, where the women lay down before he-goats (Herodotus, 2, 46; Strabo, 17, p. 802). Aelian (nat. an. vii. 19) relates an account of the crime being also committed with a dog in Rome; and according to Sonnini, R. 11, p. 330, in modern Egypt men are said to lie even with female crocodiles.

Thou shalt not lie with mankind, as with womankind: it is abomination.

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.
