Genesis 4:4-7 ASV

4 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: 5 but unto Cain and to his offering he had not respect. And Cain was very wroth, and his countenance fell. 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.
