General The New Exodus

[benadam1974]

Paul reminds the early church of what Jesus had said by rightly adding the words “as often as you drink it” in 1Cor 11:25. (NOTE the verb is in the present imperative. Its connotation is "keep on doing this in memory of me." Collins, First Corinthians, Sacra Pagina 7, 1999, p433)

The New International Commentary on the New Testament

This addition in particular implies a frequently repeated action, suggesting that from the beginning the Last Supper was for Christians not an annual Christian Passover, but a regularly repeated meal in "honor of the Lord," hence the Lord's Supper. This further tells us that Jesus had established a new institution for a new system, as foretold by the prophet Jeremiah.

This "represents and serves to reaffirm the new covenant established by Christ's sacrificial death on the cross for us. The cup was often used figuratively "of undergo-ing a violent death" (BDAG). Jesus' statement that the cup "is the new cov-enant in my blood" fuses together the language of Jeremiah 3 1:31 ("a new covenant") and Exodus 24:8 ("This is the blood of the covenant that the LORD has made with you"). The latter text refers to the establishment of the covenant at Sinai, while the former consists of God's promise to establish a new covenant in the time of postexilic restoration. By fusing the two texts together Jesus interprets his impending death as the sacrifice that estab-lishes the new covenant associated with the second exodus.
