Leviticus 18:10

"'You shall not uncover the nakedness of your son's daughter, or of your daughter's daughter, even their nakedness: for theirs is your own nakedness.

KJV

The nakedness of thy son’s daughter, or of thy daughter’s daughter, even their nakedness thou shalt not uncover: for theirs is thine own nakedness.

Commentary

The nakedness of thy son's daughter, or of thy daughter's daughter,.... A man might not marry his granddaughter, whether a descendant of his son or of his daughter, nor any further off descending from him in a right line, not his great-granddaughter, and so on; and if he might not marry his granddaughter, much less his own daughter, as Jarchi observes, for the relation is still nearer; therefore that being prohibited, this in course must, though not mentioned: even their nakedness thou shalt not uncover; neither debauch nor marry such an one: for theirs is thine own nakedness; which sprung from his, being the descendants either of his son or daughter; the Targum of Jonathan is,"for they are as thy nakedness,''his own flesh and blood.
