Genesis 4:10-16

YAHWEH said, “Listen—the voice of your brother’s blood is crying out to me from the ground! What have you done? Now you are banished from the land, from the very ground that drank your brother’s blood from your hand! When you try to cultivate the ground it will no longer produce crops for you; and you will be a fugitive, a homeless wanderer!” Cain said to YAHWEH, “My punishment is more than I can bear! Look—you’ve thrown me off the land today, and now I must hide from your presence. As a fugitive and wanderer on the earth, anyone who meets me may choose to kill me!” YAHWEH responded, “Not so! If anyone kills you, I promise the seven-fold vengeance of Cain will be released upon him!” So, YAHWEH put an identifying sign on Cain as a warning so that no one would dare kill him. Then Cain left the presence of YAHWEH and journeyed to the Land of Wandering, east of Eden.
