The New John Gill Exposition of the Entire Bible
Saying, this is the blood of the testament…
testament or covenant; this proves what the apostle had asserted in
(Hebrews 9:18) that it was dedicated with blood, or confirmed by it;
compare with this (Matthew 26:28)
which God hath enjoined unto you;
the people of Israel, to observe,
and which they promised to do; see (Exodus 24:7,8) .
