(10) The nakedness of thy son’s daughter. From this prohibition it is inferred that a man must not marry his own daughter. If a granddaughter, who is a degree further removed from him, is proscribed, how much more his own daughter. Hence the canonical law during the second Temple deduced from this passage that “whoso companieth with a woman, even by way of fornication, and begetteth a daughter, she is forbidden to him.” Still, when the mother is expressly forbidden to the son (see Lev_18:7), it is strange that the daughter should have been passed over in silence, and be left to inference. It is therefore more than probable that a word has dropped out of the text, and that originally it stood here, “the nakedness of thy daughter and of thy son’s daughter,” &c. That this is not a solitary instance where the text has suffered from disarrangement we shall presently have occasion to see in Lev_18:11.

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.

The fourth case of incest which is prohibited is that with a granddaughter, whether the daughter of son or daughter, for, as they are descended from the grandfather, their"s is thine own nakedness.

The prohibition of marriage with a granddaughter, whether the daughter of a son or daughter, is explained in the words, "for they are thy nakedness," the meaning of which is, that as they were directly descended from the grandfather, carnal intercourse with them would be equivalent to dishonouring his own flesh and blood.

ערות בת בנך THE NAKEDNESS OF THE DAUGHTER OF THY SON [OR THE DAUGHTER OF THY DAUGHTER THOU SHALT NOT UNCOVER] — When it states "thy daughter״ Scripture is speaking of his daughter born of a woman whom he had outraged (similarly "the daughter of thy son" means, the son born of such a woman). This must be so, for that one is forbidden to marry one's daughter or the daughter of one's daughter who was born of one's wife we may learn from the prohibition (v. 17) in the verse beginning אשה ובתה ערות "the nakedness of a woman and her daughter" of whom it is stated "thou shalt not uncover" and which thus implies the prohibition to marry one's daughter (and forbids one's marriage with one's daughter's daughter; for Scripture continues there: “neither shalt thou take her son's daughter or her daughter's daughter) whether she be begotten by him or by another man (cf. Yevamot 22b and Rashi von v. 17).

ערות בת בנך THE NAKEDNESS OF THY SON'S DAUGHTER [… THOU SHALT NOT UNCOVER] — Since even thy son's daughter (the former being born from an אנוסה) is forbidden, the prohibition concerning thy own daughter born of thy אנוסה could be derived by a conclusion a minori ad majus (ק״ו). But because there is a rule אין מזהירין מן הדין “no prohibition can be derived by a logical conclusion" they (the Rabbis) derived it in Treatise Yevamot 3a by an analogy (גזירה שוה) based on the similar expression הנה — הנה used here and in v. 17.
