God drove Cain out of his presence and sent him into exile far away from his native land, so that he passed from a life of human kindness to one which was more akin to the rude existence of a wild beast.
AmbroseHow far, O rich, do you extend your senseless avarice? Do you intend to be the sole inhabitants of the earth? Why do you drive out the fellow sharers of nature, and claim it all for yourselves? The earth was made for all, rich and poor, in common. Why do you rich claim it as your exclusive right?
AmbroseRemember, then, that you received a spiritual seal, the spirit of wisdom and understanding, the spirit of knowledge and reverence, the spirit of holy fear. Keep safe what you received. God the Father sealed you, Christ the Lord strengthened you and sent the Spirit into your hearts as the pledge of what is to come.
Ambrose
