17 You shall not uncover the nakedness of a woman and of her daughter, and you shall not take her son's daughter or her daughter's daughter to uncover her nakedness; they are your near kinswomen; it is wickedness. 18 And you shall not take a woman as a rival wife to her sister, uncovering her nakedness while her sister is yet alive.
19 "You shall not approach a woman to uncover her nakedness while she is in her menstrual uncleanness. 20 And you shall not lie carnally with your neighbor's wife, and defile yourself with her.
Matthew Henry's Commentary on Leviticus 18:17-20
Chapter Contents
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.
