Genesis 4:6-8

American Standard Version

⁶ And Jehovah said unto Cain, Why art thou wroth? and why is thy countenance fallen? 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 ^[a]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.
