Genesis 5:29

29. Noah This name signifies rest or comfort . The godly hope and prophetic aspiration of the Sethite, Lamech, as expressed in this name, contrast strongly with the fierce and defiant song of the warrior and polygamist of the same name, who was descended from Cain . Lamech groans under the curse of severe bodily toil, the consequence of sin . In this son he expects deliverance, and, therefore, names him Rest . Rest and deliverance came to man through Noah, but in a way that Lamech had not thought . Exactly what Lamech expected is not clear; perhaps, like Eve, he looked upon his firstborn son as the great promised Deliverer .
