Genesis 4:10

7 If thou doest well, shall it not be lifted up? and if thou doest not well, sin coucheth at the door: and unto thee shall be its desire, but do thou rule over it.

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.
