Thematic Bible: Cain fears

Behold, you have driven me out this day from the surface of the ground. I will be hidden from your face, and I will be a fugitive and a wanderer in the earth. It will happen that whoever finds me will kill me." The LORD said to him, "Therefore whoever slays Cain, vengeance will be taken on him sevenfold." the LORD appointed a sign for Cain, lest any finding him should strike him.
