"At the hand of man will I require it." By man here, we may understand, such as have greater placed and shew of reason wherewith they manage their cruelty, than those that are as the natural beast: for all persecutors are not brutish alike; some are in words as smooth as oil; others can shew a semblance of reason of state, why they should see "the righteous for silver, and the poor for a pair of shoes" (Amos 2:6). These act, to carnal reason, like men, as Saul against David, for the safety of his kingdom; but these must give an account of their cruelty, for blood is in their hands.
"At the hand of every man's brother will I require the life of man." This word brother may reach to all the apostatized hypocrites that forsake or betray the godly, for brother shall betray the brother to death (Matt 10:21). Such are spoken of in Isaiah, "Your brethren that hated you, [saith God,] and that cast you out for my name's sake, said, Let the LORD be glorified: but he shall appear to your joy, and they shall be ashamed" (Isa 65:5). So that let them be as vile as the brute, or as reasonable in appearance as men, or as near in relation as a brother; neither their ignorance, nor their reason, nor their relation to the saints, shall secure them from the stroke of the judgment of God. Ver. 6. "Whoso sheddeth man's blood, by man shall his blood be shed: for in the image of God made he man."
In these words we have both a threatening and a command; and the same words carry both: "By man shall his blood be shed," there is the threatening; "By man shall his blood be shed," there is the command. For as they threaten, so they instruct us, that he is worthy of the loss of his own blood, that doth wickedly shed the blood of another (Matt 26:52; Rev 13:10). Blood for blood, equal measure: As he also saith elsewhere, An eye for an eye, a tooth for a tooth (Exo 21:24), wound for wound, burning for burning (Lev 24:20; Deu 19:21).
"For in the image of God made he man." This seems as the reason of this equal law; because no man can slay his neighbour, but he striketh at the image of God. It is counted a heinous crime for a man to run his sword at the picture of a king, how much more to shed the blood of the image of God? "He that mocketh, or oppresseth, the poor reproacheth his Maker; but he that honoureth him, hath mercy on the poor" (Pro 14:31; 17:5). And if so, how much more do they reproach, yea, despise and abhor their Maker, that slay and murder his image! But most of all those do prove themselves the enemies of God, that make the holiness, the goodness, the religion and sobriety that is found in the people of God, the object of their wrath and hellish cruelty. Hence murder is, in the New Testament, imputed to that man that hated holy and godly man: "He that hateth his brother, is a murderer; and ye know that no murderer hath eternal life abiding in him" (1 John 3:15).
Ver. 7l. "And you, be ye fruitful, and multiply; bring forth abundantly in the earth, and multiply therein." Thus he doubleth the blessing and command, of multiplying and increasing the church in the earth, for that is the delight of God, and of Christ.
Ver. 8, 9. "And God spake unto Noah, and to his sons with him, saying, And I, behold, I establish my covenant with you, and with your seed after you."
God having thus blessed them, and given them laws and judgments to walk by, for the further confirmation of their hope in God, he propoundeth to them the immutability of his mind, by the establishing of his covenant with them; for a covenant is that, which not only concludeth the matter concerned between the persons themselves; but it provideth remedy against after temptations, and fears, and mistrusts, as to the faithful performance of that which is spoken of. As Laban said to Jacob, "Now therefore [said he] come thou, let us make a covenant, I and thou; and let it be for a witness between me and thee" (Gen 31:44). Thus also the apostle insinuates; where making mention of the promise and oath of God, he saith, this promise and oath are both immutable, that "we might have a strong consolation, [or always ground for great rejoicing] who have fled for refuge to lay hold upon the hope set before us" (Heb 6:18).
This covenant therefore, it was for the encouragement of Noah and his sons, that they might walk before God without fear. Yea, it was to maintain their hope in his promise of forgiveness, though they should find their after-performances mixed with infirmities; for so he had told them before, namely, "That he would not again destroy the earth for man's sake, albeit the imagination of man's heart be evil from his youth. I will establish my covenant with you, and with your seed after you."
Ver. 10. "And with every living creature that is with you: of the fowl, of the cattle, and of every beast of the earth with you; from all that go out of the ark, to every beast of the earth." These words respect the whole creation (see chapter 8); for all the things in the world, devils only excepted, have a benefit by this covenant of God. And hence it is, that not man only, but "every thing that hath breath," is commanded to "praise the Lord" (Psa 150:6): But observe it; as for the sin of man, they before were destroyed by the flood; so now by reason of the mercy of God to man, they are spared, and partake of mercy also. This is intimated by these words: "Every creature that is with you; every beast of the earth with you."
Ver. 11. "And I will establish my covenant with you, neither shall all flesh be cut off any more by the waters of a flood; neither shall there any more be a flood to destroy the earth."
