15 And anyone who takes as food anything which has come to a natural end, or anything which has been put to death by beasts, if he is one of you by birth, or of another nation, will have to have his clothing washed and his body bathed in water and be unclean till evening, and then he will be clean.
Matthew Henry's Commentary on Leviticus 17:15
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 But this law was ceremonial, and is now no longer in force; the coming of the substance does away the shadow.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.
