17 The nakedness of a woman and her daughter shalt thou not uncover; thou shalt not take her son's daughter, nor her daughter's daughter, to uncover her nakedness: they are her near relations: it is wickedness. 18 And thou shalt not take a wife to her sister, to vex her, to uncover her nakedness beside her, during her life.
19 And thou shalt not approach a woman in the separation of her uncleanness to uncover her nakedness. 20 And thou shalt not lie carnally with thy neighbour's wife, to become unclean 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.
