Exodus 24:8

And Moses took the blood, which had been kept in the basins, and sprinkled it on the people, and said, Behold the blood of the covenant which the Lord hath made with you concerning all these words. The significance of this solemn ceremony was that the people, through the blood of the sacrifice as it was sprinkled upon them, were received into the full fellowship with God, just as the blood poured out at the altar signified the complete surrender of the people to God. But the surrender of the people in general, as they voiced their consent to the Lord's ordinances, preceded their obedience in particular, the order which is observed to this day. We Christians are brought into true fellowship with God, not by the sacrificial blood of mere animals, but through the precious blood of Christ, as of a lamb without blemish and without spot.
