12 Thou shalt not uncover the nakedness of thy father's sister: she is thy father's near kinswoman. 13 Thou shalt not uncover the nakedness of thy mother's sister: for she is thy mother's near kinswoman. 14 Thou shalt not uncover the nakedness of thy father's brother, thou shalt not approach to his wife: she is thine aunt. 15 Thou shalt not uncover the nakedness of thy daughter-in-law: she is thy son's wife; thou shalt not uncover her nakedness. 16 Thou shalt not uncover the nakedness of thy brother's wife: it is thy brother's nakedness. 17 Thou shalt not uncover the nakedness of a woman and her daughter; thou shalt not take her son's daughter, or her daughter's daughter, to uncover her nakedness; they are near kinswomen: it is wickedness.
Matthew Henry's Commentary on Leviticus 18:12-17
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.
