Genesis 4:16-18

Young's Literal Translation

¹⁶ And Cain goeth out from before Jehovah, and dwelleth in the land, moving about east of Eden;

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.
