Irad

Irad was a descendant of Cain in the antediluvian genealogy of Genesis 4:18, listed as the son of Enoch (Cain's son, distinct from Enoch son of Jared) and the father of Mehujael. The brief lineage of Cain's line—Cain, Enoch, Irad, Mehujael, Methushael, Lamech—stands in contrast to the longer genealogy of Seth in Genesis 5 and is associated in the narrative with the development of human civilization, including city-building, music, and metalworking. Irad serves as a transitional figure in this antediluvian family tree.
