Exodus 24:5-6

"And he sent young men of the children of lsrael, who offered burnt offerings, and sacrificed peace-offerings of oxen unto Jehovah. And Moses took half of the blood, and put it in basins; and half of the blood he sprinkled on the altar."

We shall not enter into the question of whether or not these young men were the first-born, or other distinguished members of the community, for we simply are not told. Apparently, their choice was due to their youth and strength, important considerations in the size of such a sacrifice as this. They did not participate in any way in the ceremony, Moses officiating as the great priest and mediator who, as a type of Jesus Christ, sprinkled the blood. Note that the blood was sprinkled, not merely upon the altar, but upon the people also. Thus, Christ offered his blood in heaven as an atonement once for all for the sins of mankind, and yet, it is that same blood of Christ by which the hearts of all true believers are "sprinkled" (Hebrews 10:19-22).

"Burnt offerings, and peace offerings ..." The multiple sacrifices were not only numerous, but of various kinds. Although sin-offering is not specifically mentioned here, there was nevertheless inherent in all sacrifices, especially of blood sacrifices, the admission of human sin and guilt. It was therefore appropriate that prior to the blood-rite confirming the covenant these offerings acknowledging the sins of Israel should have been offered. Esses even affirmed that "Because there was sin in Israel, the sin offering had to be made before the burnt offering."[12] Certainly, we must reject the notion that "They were a redeemed people, "[13] and therefore did not need to offer a sin offering!

"Half of the blood he sprinkled on the altar ..." This was the first of the double sprinkling, the other being related in the next verses.
