Finally, the establishment of the covenant was celebrated by a formal congratulatory dinner, at which God was the host and the representatives of the people were the guests (Exo 24:9-11).

And as they were eating, Jesus took bread, and blessed it, and brake it, and gave it to the disciples, and said, Take, eat; this is My Body. ^{And He took the cup, and gave thanks, and gave it to them, saying, Drink ye all of it; For this is My Blood of the New Covenant, which is shed for many for the remission of sins.}
