Misinterpretations often confuse this cup with the one representing Christ's blood in communion, as it is actually the preliminary Passover cup shared before the bread and the later covenant cup in verse 20, leading some to isolate it as mere promotion of wine drinking while ignoring its role in the ritual sequence and Jewish context of remembrance and preparation for deliverance.
Luke 22:17
King James Version (1769)
17 And he took the cup, and gave thanks, and said, Take this, and divide it among yourselves:
During the Last Supper, a Passover meal, Jesus takes a cup, gives thanks, and instructs his disciples to divide it among themselves, highlighting themes of communal sharing, blessing, and fellowship as he prepares them for the new covenant established through his sacrificial death, symbolizing unity in anticipation of redemption.
