"What hast thou done?" the blood of thy brother cries. Beware persecutors, you think that when you have slain the godly, you are then rid of them; but you are far wide, their blood which you have shed, cries in the ears of God against you. O the cries of blood are strong cries, they are cries that reach to heaven; yea they are cries that have a continual voice, and that never cease to make a noise, until they have procured vengeance form the hands of the Lord of sabbath (Job 16:18): And therefore this is the word of the Lord against all those that are for the practice of Cain: "As I live, saith the Lord God, I will prepare thee unto blood and blood shall pursue thee: sith thou hast not hated blood, [that is, hated to shed it,] even blood shall pursue thee" (Eze 35:6).
"The voice of thy brother's blood crieth unto me." The apostle makes this voice of the blood of Abel, a type of the voice of the justice of the law, and so extends it further than merely to the act of murder; intimating that he sheds blood, that breaks any of the commands of God, (and indeed so he doth, "he layeth wait of his own blood, and privily lurketh for his own life" (Prov 1:18)). Wherefore the apostle compareth the blood of Abel and the blood of Christ together; but so as by the rule of contraries, making betwixt them a contrary voice, even as there is between a broken command and a promise of grace, the one calling for vengeance and damnation; the other calling for forgiveness and salvation; "the blood of sprinkling it speaketh better things than the blood of Abel" (Heb 12:24); that is, it calls to God to forgive the sinner; but Abel's blood, of the breach of the law, that cries damn them, damn them. Christ also sets his own blood in opposition to the blood of all that was shed before him; concluding that the proper voice of all the blood of the godly, is to call for vengeance on the persecutors, even from the blood of Abel to the blood of Zecharias, that was slain between the altar and the temple (Matt 23:35). And let me here take leave to propound my private thoughts: namely, that the Zecharias that here is mentioned, might not be he that we find in the book of Chronicles (2 Chron 24:21); but one of that name that lived in the days of Christ, possibly John Baptist's father, or some other holy man. My reasons for this conjecture, are, 1. Because the murderers are convict by Christ himself: Zecharias, whom ye slew between the altar and the temple. 2. Because Christ makes a stop at the blood of Zecharias, not at the blood of John the Baptist: wherefore, if the person here mentioned were not murdered after, but before John the Baptist, then Christ seems to excuse them for killing his servant John; for the judgment stops at the including of the guilt of the blood of Zecharias. 3. I think such a thing, because the voice of all holy blood that hath been shed before the law by the adversary, excepting only the blood of Jesus, must needs be included here; the proper voice of his, only being to plead for mercy to the murderers. However, the voice of blood is a very killing voice, and will one day speak with such thunder and terror in the consciences of all the brood of Cain, that their pain and burthen will be for ever insupportable.
Ver. 11. "And now art thou cursed from the earth, which hath opened her mouth to receive thy brother's blood from thy hand."
Here begins the sentence of God against this bloody man; a sentence fearful and terrible, for it containeth a removing of him from all the privileges of grace and mercy, and a binding of him over to the punishment and pains of the damned.
"And now art thou cursed from the earth." Peace on earth, is one branch of those blessed tidings that were brought into the world, at the coming of the Messias (Luke 2:14). Again, before Christ was come in the flesh, it is said, He rejoiced "in the habitable part of his earth" (Pro 8:30). Wherefore, by the earth in this place, I understand the state that the men are in, to whom, by the mind of God, the gospel and grace of God is to be tendered. Now, whether it respect that state of man by nature, or the state of those that are saints, from both these privileges Cain is separate, as are all whom the Lord hath utterly rejected. Not but that yet they may live long in the world, but God hath cut them off from the earth, and all the gospel privileges therein, and set them in the condition of devils; so that as to grace and mercy they are separate therefrom, and stand as men, though alive, bound over to eternal judgment. And as to their lives, it matters not how long they live, there is "no sacrifice for their sins, but a certain fearful looking for of judgment and fiery indignation, which shall devour the adversaries" (Heb 10:26,27). So that I say, as the devils be bound in hell, so such lie bound in earth; bound I say in the chains of darkness, and their own obstinate heart, over to the day of wrath and revelation of the righteous judgment of God. Cain therefore by these words is denied the blessing of future means of grace, and stands bound over to answer for his brother's blood, which the ground had received form his cruel hand.
Ver. 12. "When thou tillest the ground, it shall not henceforth yield to thee her strength; a fugitive and a vagabond shalt thou be in the earth."
This is a branch, or the fruits of this wilful murder. Indeed, sins carry in them not only a curse with respect to eternity, but are also the cause of all the miseries of this life. "God turneth—a fruitful land into barrenness, for the wickedness of them that dwell therein" (Psa 107:34).
"When thou tillest the ground." Sin committed doth not always exclude the sinner from an enjoyment of God's mercies, but yet if unrepented of, bringeth a curse upon them. "I will curse, [saith God,] your blessings: yea, I have cursed them already, because ye do not lay it to heart" (Mal 2:2). This also is the reason that the table of some is made their snare, their trap, a stumbling-block and a recompence unto them (Rom 11:9); men ought not therefore to judge of the goodness of their state, by their enjoyment of God's creatures, but rather should tremble while they enjoy them, lest for sin they should become accursed to them, as were the enjoyments of this wicked man.
"A fugitive and a vagabond shalt thou be in the earth." The meaning is, thou shalt not have rest in the world, but shalt be continually possessed with a guilty conscience, which shall make thy condition restless, and void of comfort. For the man that indeed is linked in the chains of guilt and damnation, as Cain here was; he cannot rest, but (as we say) fudge up and down from place to place, because his burthen is insupportable. As David said, "Let their eyes be darkened that they see not, and make their loins continually to shake" (Psa 69:23). A continual shaking and restlessness doth therefore possess such persons as are given up of God, and swallowed up of guilt.
"A fugitive and vagabond shalt thou be in the earth." Some men certainly know, even while they are in this world, their state to be most miserable, and damnable, as Cain, Saul and Judas did; which knowledge, as I have hinted, puts them besides the very course of other carnal men; who while they behold them at quiet under their enjoyments, these cannot but wonder, fear, and be amazed with the deep cogitations which will abide upon them, of their certain misery and everlasting perdition.
