Hebrews 11:4

And in process of time it came to pass, that Cain brought of the fruit of the ground an offering unto the Lord. 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: But unto Cain and to his offering he had not respect. And Cain was very wroth, and his countenance fell.

And to Jesus the mediator of the new covenant, and to the blood of sprinkling, that speaketh better things than that of Abel.

For this is the message that ye heard from the beginning, that we should love one another. Not as Cain, who was of that wicked one, and slew his brother. And wherefore slew he him? Because his own works were evil, and his brother’s righteous.

And he said, What hast thou done? the voice of thy brother’s blood crieth unto me from the ground.

Woe unto them! for they have gone in the way of Cain, and ran greedily after the error of Balaam for reward, and perished in the gainsaying of Core.

That upon you may come all the righteous blood shed upon the earth, from the blood of righteous Abel unto the blood of Zacharias son of Barachias, whom ye slew between the temple and the altar.

The sacrifice of the wicked is an abomination to the Lord: but the prayer of the upright is his delight.

And the Lord said unto him, Therefore whosoever slayeth Cain, vengeance shall be taken on him sevenfold. And the Lord set a mark upon Cain, lest any finding him should kill him.

And Cain talked with 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 almost all things are by the law purged with blood; and without shedding of blood is no remission.

Then the fire of the Lord fell, and consumed the burnt sacrifice, and the wood, and the stones, and the dust, and licked up the water that was in the trench.

And Adam knew his wife again; and she bare a son, and called his name Seth: For God, said she, hath appointed me another seed instead of Abel, whom Cain slew.

Wherefore seeing we also are compassed about with so great a cloud of witnesses, let us lay aside every weight, and the sin which doth so easily beset us, and let us run with patience the race that is set before us,

And there came a fire out from before the Lord, and consumed upon the altar the burnt offering and the fat: which when all the people saw, they shouted, and fell on their faces.

From the blood of Abel unto the blood of Zacharias, which perished between the altar and the temple: verily I say unto you, It shall be required of this generation.

The sacrifice of the wicked is abomination: how much more, when he bringeth it with a wicked mind?

They profess that they know God; but in works they deny him, being abominable, and disobedient, and unto every good work reprobate.
