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.
In this chapter the Israelites are directed in general not to imitate the customs and practices of the Egyptians and Canaanites, but to keep the ordinances, statutes, and judgments of the Lord, Le 18:1-5; and they are instructed particularly to avoid incestuous marriages, Le 18:6-18; carnal copulation with a menstruous woman, Le 18:19; adultery, Le 18:20; letting any of their seed pass through the fire to Molech, Le 18:21; sodomy, Le 18:22; and bestiality, Le 18:23; and they are deterred from these things by observing to them the pollution and destruction which they brought on the inhabitants of Canaan, and would bring the same on them should they commit them, Le 18:24-30.
