Exodus 24:8

24:8 So Moses took the blood and splashed it on ¹  the people and said, “This is the blood of the covenant ²  that the Lord has made with you in accordance with all these words.”

Exodus 29:20

29:20 and you are to kill the ram and take some of its blood and put it on the tip of the right ear of Aaron, on the tip of the right ear of his sons, on the thumb of their right hand, and on the big toe of their right foot, ³  and then splash the blood all around on the altar.

[24:8]  ¹ tn Given the size of the congregation, the preposition might be rendered here “toward the people” rather than on them (all).

[24:8]  ² sn The construct relationship “the blood of the covenant” means “the blood by which the covenant is ratified” (S. R. Driver, Exodus, 254). The parallel with the inauguration of the new covenant in the blood of Christ is striking (see, e.g., Matt 26:28, 1 Cor 11:25). When Jesus was inaugurating the new covenant, he was bringing to an end the old.

[29:20]  ³ sn By this ritual the priests were set apart completely to the service of God. The ear represented the organ of hearing (as in “ears you have dug” in Ps 40 or “awakens my ear” in Isa 50), and this had to be set apart to God so that they could hear the Word of God. The thumb and the hand represented the instrument to be used for all ministry, and so everything that they “put their hand to” had to be dedicated to God and appropriate for his service. The toe set the foot apart to God, meaning that the walk of the priest had to be consecrated – where he went, how he conducted himself, what life he lived, all belonged to God now.
