Exodus 24:6

1. The blood of the sacrifice which the people offered was (part of it) sprinkled upon the altar, which signified the people's dedicating themselves to God, and his honour. In the blood of the sacrifices, all the Israelites were presented unto God as living sacrifices, Romans 12:1 Romans 2:1. The blood of the sacrifice which God had owned and accepted was (the remainder of it) sprinkled, either upon the people themselves, or upon the pillars that represented them, which signified God's conferring his favour upon them, and all the fruits of that favour, and his giving them all the gifts they could desire from a God reconciled to them, and in covenant with them. This part of the ceremony was thus explained, Behold the blood of the covenant; see here how God sealed to you to be a God, and you seal to be to him a people; his promises to you, and yours to him, are yea and amen. Thus our Lord Jesus, the Mediator of the new covenant (of whom Moses was a type) having offered up himself a sacrifice upon the cross, that his blood might be indeed the blood of the covenant, sprinkled it upon the altar in his intercession (Hebrews 9:12,) and sprinkles it upon his church by his word and ordinances, and the influences and operations of the Spirit of promise by whom we are sealed.
