Leviticus 18:12 Meaning and Commentary

Leviticus 18:12

Thou shalt not uncover the nakedness of thy father's sister,
&c.] His aunt by his father's side, an instance of which we have in Amram, ( Exodus 6:20 ) ; and Maimonides says ^F9, an aunt was forbidden whether she was a father's sister in lawful wedlock or in fornication: she [is] thy father's near kinswoman;
or, the rest of thy father ^F11; the residue of his flesh, one of the same flesh and blood with him; wherefore, as he could not marry her himself, so his son likewise was too near akin to enter into such a relation with her.
