Genesis Chapter 4

8 And Cain told Abel his brother. And it came to pass, when they were in the field, that Cain rose up against Abel his brother, and slew him.

9 And Jehovah said unto Cain, Where is Abel thy brother? And he said, I know not: am I my brother's keeper?

10 And he said, What hast thou done? the voice of thy brother's blood crieth unto me from the ground.

11 And now cursed art thou from the ground, which hath opened its mouth to receive thy brother's blood from thy hand;

12 when thou tillest the ground, it shall not henceforth yield unto thee its strength; a fugitive and a wanderer shalt thou be in the earth.

13 And Cain said unto Jehovah, My punishment is greater than I can bear.
