GENESIS 4:25-26 (KJV)

²⁵And Adam knew his wife again; and she bare a son, and called his name Shet: For God, said she, hath appointed me another seed instead of Hevel, whom Qayin slew. ²⁶And to Shet, to him also there was born a son; and he called his name Enos: then began men to call upon the name of YHVH.
