John Gill Commentary Luke 22:20

"And the cup in like manner after supper, saying, This cup is the new covenant in my blood, [even] that which is poured out for you." — Luke 22:20 (ASV)

Likewise also the cup after supper Both after the passover, and the Lord's supper; that is, he took the cup after they had eaten the bread, and gave thanks over it, and gave it to his disciples, bidding them drink of it, as in (Matthew 26:27) , (See Gill on Matthew 26:27): saying, this cup is the New Testament in my blood, which is shed for you . The Ethiopic version reads, "for many"; as in (Matthew 26:28) where it is added, "for the remission of sins"; (See Gill on Matthew 26:28).
