Genesis 4:26 - Wesley's Explanatory Notes

And to Seth was born a son called Enos, which is the general name for all men, and speaks the weakness, frailty, and misery of man's state. Then began men to call upon the name of the Lord — Doubtless God's name was called upon before, but now, 1. The worshippers of God began to stir up themselves to do more in religion than they had done; perhaps not more than had been done at first, but more than had been done since the defection of Cain. Now men began to worship God, not only in their closets and families, but in public and solemn assemblies. 2. The worshippers of God began to distinguish themselves: so the margin reads it. Then began men to be called by the name of the Lord, or, to call themselves by it. Now Cain and those that had deserted religion had built a city, and begun to declare for irreligion, and called themselves the sons of men. Those that adhered to God began to declare for him and his worship, and called themselves the sons of God.
