Parallel
Leviticus 18:17
Clementine Vulgate · Berean Standard Bible
Turpitudinem uxoris tuæ et filiæ ejus non revelabis. Filiam filii ejus, et filiam filiæ illius non sumes, ut reveles ignominiam ejus : quia caro illius sunt, et talis coitus incestus est.
You must not have sexual relations with both a woman and her daughter. You are not to marry her son’s daughter or her daughter’s daughter and have sexual relations with her. They are close relatives; it is depraved.
