Genesis 9:4

These divine purposes of peace, which were communicated to Noah while sacrificing, were solemnly confirmed by the renewal of the blessing pronounced at the creation and the establishment of a covenant through a visible sign, which would be a pledge for all time that there should never be a flood again. In the words by which the first blessing was transferred to Noah and his sons (Gen 9:2), the supremacy granted to man over the animal world was expressed still more forcibly than in Gen 1:26 and Gen 1:28; because, inasmuch as sin with its consequences had loosened the bond of voluntary subjection on the part of the animals to the will of man-man, on the one hand, having lost the power of the spirit over nature, and nature, on the other hand, having become estranged from man, or rather having rebelled against him, through the curse pronounced upon the earth-henceforth it was only by force that he could rule over it, by that "fear and dread" which God instilled into the animal creation. Whilst the animals were thus placed in the hand (power) of man, permission was also given to him to slaughter them for food, the eating of the blood being the only thing forbidden.

Both the world and the church were now again reduced to a family, the family of Noah, of the affairs of which this chapter gives us an account, of which we are the more concerned to take cognizance because from this family we are all descendants. Here is, I. The covenant of providence settled with Noah and his sons (Gen 9:1-11). In this covenant, 1. God promises them to take care of their lives, so that, (1.) They should replenish the earth (Gen 9:1, Gen 9:7). (2.) They should be safe from the insults of the brute-creatures, which should stand in awe of them (Gen 9:2). (3.) They should be allowed to eat flesh for the support of their lives; only they must not eat blood (Gen 9:3, Gen 9:4). (4.) The world should never be drowned again (Gen 9:8-11). 2. God requires of them to take care of one another's lives, and of their own (Gen 9:5, Gen 9:6). II. The seal of that covenant, namely, the rainbow (Gen 9:12-17). III. A particular passage of story concerning Noah and his sons, which occasioned some prophecies that related to after-times, 1. Noah's sin and shame (Gen 9:20, Gen 9:21). 2. Ham's impudence and impiety (Gen 9:22). 3. The pious modesty of Shem and Japheth (Gen 9:23). 4. The curse of Canaan, and the blessing of Shem and Japheth (Gen 9:21-27). IV. The age and death of Noah (Gen 9:28, Gen 9:29).

9:4 A key restriction is imposed. Since blood was identified with life, it had to be drained from a slain animal before its meat could be eaten (see Lev 3:17; 7:26-27; 17:10-14; Deut 12:16, 23). The law of Moses prohibited eating animals that died naturally, since their blood had not been drained (Deut 14:21). God provided animal blood to atone for human sin (Lev 17:11; Heb 9:22).
