"Every moving thing." This must be taken with this restriction, That is wholesome and good for food: for by the law of nature, nothing of that is forbidden to man, though for some significations many such creatures were forbidden us to use for a time (Deu 14).
"Even as the green herb." For which they expressly had liberty granted them, in the first chapter of this book (v 29). And this liberty might afresh be here repeated, from some scruple that might arise in Noah, &c. He remembering that the world before might, for the abuse of the creatures of God, as well as for the abuse of his worship, be drowned with the flood; for sometimes the abuse of that which is lawful to one, may be a snare, abuse and stumbling to another (1 Cor 7:1; 8).
Ver. 4. "But flesh with the life thereof, which is the blood thereof shall ye not eat."
This law seems to be ceremonial, although given long before Moses was; as also some sacrifices and circumcision were (John 7:22). Wherefore we must seek for the reason of this prohibition. "Whatsoever man [saith God] there be of the house of Israel,—that eateth any manner of blood, I will even set my face against that soul that eateth blood, and will cut him off from among his people." Why? "For the life of the flesh is in the blood: and I have given it to you upon the altar to make an atonement for your souls: for it is the blood that maketh an atonement for the soul. Therefore I said unto the children of Israel, No soul of you shall eat blood" (Lev 17:10-12). Again, As here the prohibition is only concerning blood; so in another place, the word is as well against our eating the fat; "It shall be a perpetual statute for your generations, throughout all your dwellings, that ye neither eat fat nor blood." And the reason rendered, is, For "all the fat is the LORD'S" (Lev 3:16,17).
So then the meaning, the spiritual meaning, seems to be this, That forasmuch as the blood is the life, and that which maketh the atonement; and the fat, the glory, and the Lord's; therefore they both were to be offered to the Lord. That is, we ought always to offer the merit of our salvation to God, by a continual acknowledgment, that it was through the blood of Christ; and we ought always to give him the glory thereof, and this is the fat of all our performances (Isa 25:6). Now this is so blessed a thing, and calleth for that grace, that every professor hath not, every one cannot ascribe to the blood of the Lamb, the whole of his reconciliation to God; nor offer up the fat, the glory, which is God's, to the Lord for so great a benefit: this is the benefit of a peculiar people, even of "the priests the Levites, the sons of Zadok, [or they that are justified, or just thereby; (For so Zadok signifies)] that kept the charge of my sanctuary, when the children of Israel went astray from me; they shall come near to me, to minister unto me, and they shall stand before me to offer unto me the fat and the blood, saith the Lord God" (Eze 44:15).
Wherefore, for men to ascribe to their own works the merit of their salvation, or to take the glory thereof to themselves; it is as eating the blood and the fat themselves, and they shall be cut off from the people of God.
Ver. 5. "And surely your blood of your lives will I require; at the hand of every beast will I require it, and at the hand of man; at the hand of every man's brother, will I require the life of man."
These words are spoken to the church, which then resided in this family: Not but that God will avenge the blood that is wrongfully shed, though the person murdered be most carnal and irreligious. "A man that doeth violence to the blood of any person, shall flee to the pit; let no man stay him" (Pro 28:17).
But I say, these words respect the church in a more special and eminent way. "Surely [saith God] your blood of your lives will I require." Thus also David insinuates the thing: "when he maketh the inquisition for blood, he remembereth them: [the saints and godly in special,] he forgetteth not the cry of the humble," the afflicted (Psa 9:12).
"At the hand of every beast will I require it." The beasts are here also to be taken for men, to whom they are frequently likened in scripture; and that because they have cast off human affections; and, like savage creatures, make a prey of those that are better than themselves. Ignorance therefore or brutishness, O thou wicked man! will not excuse thee in the day of judgment; all the injuries that thou doest to the people of God, shall for certain be required of thee.
