Leviticus 20:17 And if a man shall take his sister, his father's daughter, or his mother's daughter, and see her nakedness, and she see his nakedness; it is a wicked thing; and they shall be cut off in the sight of their people: he hath uncovered his sister's nakedness; he shall bear his iniquity. Seeing
is here understood, either,
1. Properly, and so God would cut off the occasions of further filthiness. Or rather,
2. Improperly, for touching her or lying with her; for,
1. The sense of
seeing
is oft put for other senses, as for
hearing,
Genesis 42:1, compared with
Acts 7:12 Exodus 20:18 Revelation 1:12; and for
touching, as
John 20:25 ,29.
2. That act is expressed by words parallel to this of
seeing, as by
uncovering, or
discovering, and by
knowing,
Genesis 4:1.
3. So it is directly explained in the following words,
he hath uncovered his sister’s nakedness,
which manifestly signifies lying with her.
4. It is not probable that an equal punishment would have been appointed to an immodest sight, and to the highest act of filthiness.
5. Nor seems there to be any reason why this crime should be restrained to this rather than to any other relations, when it was as great, yea, a greater crime in some other relations.
In the sight of their people, i.e. publicly, for the terror and caution of others.
