¹⁷ and Cain knoweth his wife, and she conceiveth, and beareth Enoch; and he is building a city, and he calleth the name of the city, according to the name of his son -- Enoch.

¹⁸ And born to Enoch is Irad; and Irad hath begotten Mehujael; and Mehujael hath begotten Methusael; and Methusael hath begotten Lamech.

¹⁹ And Lamech taketh to himself two wives, the name of the one Adah, and the name of the second Zillah.
