Blood: To blood is ascribed in Scripture the mysterious sacredness which belongs to life, and God reserved it to himself when allowing man the dominion over and the use of the lower animals for food. Thus reserved, it acquires a double power: (1) that of sacrificial atonement; and (2) that of becoming a curse when wantonly shed, unless duly expiated. (Genesis 9:4; Leviticus 7:26; 17:11-13)
