10 And if any man of Israel, or any other living among them, takes any sort of blood for food, my wrath will be turned against that man and he will be cut off from among his people. 11 For the life of the flesh is in its blood; and I have given it to you on the altar to take away your sin: for it is the blood which makes free from sin because of the life in it. 12 For this reason I have said to the children of Israel, No man among you, or any others living with you, may take blood as food.
Matthew Henry's Commentary on Leviticus 17:10-12
Commentary on Leviticus 17:10-16
(Read Leviticus 17:10-16)
Here is a confirmation of the law against eating blood. They must eat no blood. But this law was ceremonial, and is now no longer in force; the coming of the substance does away the shadow. The blood of beasts is no longer the ransom, but Christ's blood only; therefore there is not now the reason for abstaining there then was. The blood is now allowed for the nourishment of our bodies; it is no longer appointed to make an atonement for the soul. Now the blood of Christ makes atonement really and effectually; to that, therefore, we must have regard, and not consider it as a common thing, or treat it with indifference.
