On the occasion of the inauguration of the covenant, Moses officiated, directing the sacrifice of the animals. Then he sprinkled their blood on the scroll or “the book of the covenant.” He read the book to the people, setting forth the terms, and the people responded by agreeing to obey. Moses then sprinkled them (doubtless the representative older men) with the blood, saying: “Here is the blood of the covenant that Jehovah has concluded with you as respects all these words.”​—Ex 24:3-8; Heb 9:18-22.

In harmony with the pattern followed at the inauguration of the Law covenant, Jesus Christ presented the value of his sacrifice before God in heaven (even as Moses sprinkled the blood on the book of the Law [for God was not personally present there]).

Heb 9:19)
