Place in the Genealogy
Enos stands in the third generation after Adam: he was the son of Seth, the son whom Genesis presents as born to Adam and Eve in the place of Abel. Genesis 5 records his place in the long pre-flood line of patriarchs. Through his son Kenan, the line continued by way of Mahalalel, Jared, Enoch, Methuselah, and Lamech to Noah.
The New Testament carries this same descent forward: the genealogy of Jesus in the Gospel of Luke (Luke 3:38) names Enos in the line traced back through the patriarchs to Adam. It is on this account that the Church numbers him among the Forefathers of Christ.
