“Only be sure that thou eat not the blood: for the blood is the life; and thou mayest not eat the life with the flesh.”
King James Version (KJV)
12:21 If the place be too far - Being obliged to carry their sacrifices to the place of worship, they might think themselves obliged to carry their other cattle thither to be killed. They are therefore released from all such obligations, and left at liberty to kill them at home, whether they lived nearer that place, or farther from it; only the latter is here mentioned, as being the matter of the scruple. As I have commanded - In such a manner as the blood may be poured forth.
12:22 As the roe - buck - As common or unhallowed food, tho' they be of the same kind with the sacrifices which are offered to God. The unclean - Because there was, no holiness in such meat for which the unclean might be excluded from it.
