The sanctity of blood.
The central altar was for the reception of the blood. And while the Jews remained in pilgrimage, every time they killed an animal out of their flocks or herds for family use they carried the blood to the tabernacle, that it might be duly disposed of by the priest. In case of the roebucks and harts, their blood was not sacrificial; it was therefore ordained that it should be poured out on the earth, and carefully and solemnly covered up. When they were settled in the land of Canaan, they were too far from the central altar to carry the blood of every animal out of the herd or flock which was slain to the appointed place. Hence they were allowed to deal with the domestic animals as with the products of the chase (Deuteronomy 12:22). It is to this fact of the sanctity of blood that we would now direct attention.
I. THE HEATHEN NATIONS WERE ACCUSTOMED TO MAKE DRINK OFFERINGS OF BLOOD. David refers to the fact when he says, "Their sorrows shall be multiplied that hasten after another god: their drink offerings of blood will I not offer, nor take up their names into my lips" (Psalms 16:4). These drink offerings of blood arose, doubtless, out of the bloodthirstiness of the heathen themselves. Men of blood thought their god delighted in blood shedding as they did; it was human passion projected into the religious domain.
II. GOD SO DIRECTED HIS WORSHIPPERS ABOUT THE DISPOSAL OF THE BLOOD THAT THEY COULD NOT REGARD IT IN ANY OTHER LIGHT THAN AS A MOST SACRED THING. It was to be carefully carried to his altar and disposed of by the officiating priests, or, if this was not possible, it was solemnly poured into the earth, and covered carefully from all profane uses. On no account was it to be eaten: this would have profaned it.
III. THE REASON ASSIGNED WAS THAT THE LIFE WAS IN THE BLOOD. "Life" is the gift of God, the mysterious something which escapes our observation in analysis, which baffles our productive powers, and which works such wonders in the world of nature. As God's gift, it is to be holy in our eyes, and disposed of as he sees best.
IV. THE VICARIOUSNESS OF SUFFERING GAVE IT ADDITIONAL SANCTITY. For shed blood meant life sacrificed to sustain other life. Our bodies depend upon vicarious suffering for their sustenance. Sacrifice underlies the constitution of the world. It was meet, then, that this principle should be recognized and sanctified in the sight of men.
V. BLOOD HAD ITS RELIGIOUS FUNCTION, NOT A PHYSICAL FUNCTION, TO DISCHARGE IN THE MOSAIC ECONOMY. The God of Israel did not delight in blood, as the gods of the heathen were supposed to do. He singled it out for a religious use. It was to be the material of a holy act, wherever shed. This was undoubtedly to keep it so out of the sphere of physical elements that it could symbolize fully "the blood of Jesus Christ," by which the world is to be saved.—R.M.E.
