Genesis, Chapter 4
Verses 25 - 26
25 - And Adam knew his wife again; and she bare a son, and called his name Seth: For God, said she, hath appointed me another seed instead of Abel, whom Cain slew.
26 - And to Seth, to him also there was born a son; and he called his name Enos: then began men to call upon the name of the LORD.
