Genesis 4:11

Cain said to Abel, his brother, “Let’s go into the field.” While they were in the field, Cain rose up against Abel, his brother, and killed him.

The LORD said to Cain, “Where is Abel, your brother?”

He said, “I don’t know. Am I my brother’s keeper?”

The LORD said, “What have you done? The voice of your brother’s blood cries to me from the ground.

From now on, when you till the ground, it won’t yield its strength to you. You will be a fugitive and a wanderer on the earth.”

Cain said to the LORD, “My punishment is greater than I can bear.

Behold, you have driven me out today from the surface of the ground. I will be hidden from your face, and I will be a fugitive and a wanderer on the earth. Whoever finds me will kill me.”
