17 You shall not uncover the nakedness of a woman and her daughter, nor shall you take her son's daughter or her daughter's daughter, to uncover her nakedness. They are near of kin to her. It is wickedness. 18 Nor shall you take a woman as a rival to her sister, to uncover her nakedness while the other is alive.
19 'Also you shall not approach a woman to uncover her nakedness as long as she is in her customary impurity. 20 Moreover you shall not lie carnally with your neighbor's wife, to 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.
