Exodus 24:6 - Joseph Benson’s Commentary on the Old and New Testaments

1st, 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. 2d, The blood of the sacrifice which God 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. 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, sprinkles it upon the altar in his intercession, (Hebrews 9:12,) and sprinkles it upon his church by his word and ordinance, and operations of the Spirit of promise, by whom we are sealed to be to him a people.
