Exodus 24:8

“And Moses took the blood, etc.] The other half of the blood which was in the basins: and sprinkled it on the people; not on the whole body of the people, who could not be brought nigh enough, and were too numerous to be all sprinkled with it; though the apostle so expresses it, a part being put for the whole, (<580919>Hebrews 9:19) either this was sprinkled on the young men that offered the sacrifices in the name of all the people; or on the seventy elders, as the heads of them, so Aben Ezra; or upon the twelve pillars, which answered to the twelve tribes, and represented them as the altar did the Lord: and said, behold the blood of the covenant, which the Lord hath made with you concerning…”
