The grandson of Adam. He lived nine hundred and five years. Adam, Seth, and Enoch died before him; and Noah was contemporary with him eighty-four years, Genesis 4:26; 5:6-11; Luke 3:38 . In his days "began men to call upon the name of the Lord" in organized and systematic public worship; then began men to call themselves by the name of the Lord; that is, for the purpose of marking the distinction between men of God and the ungodly.
