Hebrews 9:20

This is the blood of the testament - (covenant.) Our Lord refers to the conduct of Moses here, and partly quotes his words in the institution of the eucharist: This is my blood of the new covenant, which is shed for many for the remission of sins, Matthew 26:28. And by thus using the words and applying them, he shows that his sacrificial blood was intended by the blood shed and sprinkled on this occasion, and that by it alone the remission of sins is obtained.

Saying, This is the blood of the testament - Of the covenant; see notes on Hebrews 9:16-17. That is, this is the blood by which the covenant is ratified. It was the means used to confirm it; the sacred and solemn form by which it was made sure. When this was done, the covenant between God and the people was confirmed - as a covenant between man and man is when it is sealed.

Which God hath enjoined unto you - In Exodus 24:8, "which God hath made with you." The language used by Paul, "which God hath enjoined" - ἐνετείλατο eneteilato - "commanded" - shows that he did not regard this as strictly of the nature of a "covenant," or "compact." When a compact is made between parties, one does not "enjoin" or "command" the other, but it is a mutual "agreement." In the transactions between God and man, though called בּרית beriyt, or διαθήκη diathēkē, the idea of a "covenant" or "compact" is so far excluded that God never loses his right to "command" or "enjoin." It is not a transaction between equals, or an "agreement;" it is a solemn "arrangement" on the part of God which he proposes to mankind, and which he enjoins them to embrace; which they are not indeed at liberty to disregard, but which when embraced is appropriately ratified by some solemn act on their part; compare notes on Hebrews 8:6.

9:20 Saying, This is the blood of the covenant which God hath enjoined me to deliver unto you - By this it is established. Ex 24:8.
