Behold, you have driven me today away from the ground, and from your face I shall be hidden. I shall be a fugitive and a wanderer on the earth, and whoever finds me will kill me.
-- Genesis 4:14 (ESV)
In Gen 4, the only children Adam and Eve had were Cain and Abel, yet in this verse Cain was afraid that everyone who finds him would slay him. Who are the people that Cain was afraid would slay him?
