Genesis 7:5

All that the Lord commanded him. As Noah had fulfilled all commands of God during the previous 120 years (see ch. 6:22), so he acted in like manner during the last hours before the Flood came. How much he must have suffered as he saw the multitude of human beings with whom he had lived for six centuries, indifferently and carelessly drifting to their doom! Knowing that all of them were to die at the end of one week, and seeing them carouse as if nothing would happen (Matt. 24:37-39), he must have redoubled his final efforts to warn and invite them to enter the ark with him. But all was to no avail.
