Genesis 4:2-12

And again she bare his brother Abel. And Abel was a keeper of sheep, but Cain was a tiller of the ground. And in process of time it came to pass, that Cain brought of the fruit of the ground an offering unto Jehovah. And Abel, he also brought of the firstlings of his flock and of the fat thereof. And Jehovah had respect unto Abel and to his offering: but unto Cain and to his offering he had not respect. And Cain was very wroth, and his countenance fell. And Jehovah said unto Cain, Why art thou wroth? and why is thy countenance fallen? 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. 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. And Jehovah said unto Cain, Where is Abel thy brother? And he said, I know not: am I my brother’s keeper? And he said, What hast thou done? the voice of thy brother’s blood crieth unto me from the ground. And now cursed art thou from the ground, which hath opened its mouth to receive thy brother’s blood from thy hand; 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.
