Hebrews 9:20

So Moses took the blood and sprinkled it on the people and said, “Behold the blood of the covenant, which Yahweh has cut with you in accordance with all these words.”

He also brought Aaron’s sons near; and Moses put some of the blood on the lobe of their right ear and on the thumb of their right hand and on the big toe of their right foot. Moses then splashed the rest of the blood around on the altar.

for this is My blood of the covenant, which is poured out for many for forgiveness of sins.
