Genesis 4 v 3 And in process of time it came to pass, that Cain brought of the fruit of the ground an offering unto the LORD. 4 And Abel, he also brought of the firstlings of his flock and of the fat thereof. And the LORD had respect unto Abel and to his offering: 5 But unto Cain and to his offering he had not respect.
