Passover and covenant language locate the meal within Israel's foundational story of redemption. Shared bread and wine become Jesus' enacted interpretation of his approaching death.
The scene is not merely a prediction; Jesus institutes a continuing communal action centered on himself.
Exodus 24:8 records Moses sprinkling sacrificial blood and declaring, 'Behold the blood of the covenant' that the LORD has made with Israel.
Jesus deliberately echoes that language but identifies the covenant blood with his own impending sacrificial death.
Jesus gives bread as representing his body and the cup as his covenant blood poured out for many. The covenant's saving significance is thus centered upon Jesus' own person and death.
The action also interprets the Passion before it occurs, showing that Jesus understands his death as purposeful rather than accidental.
Establishing the covenant in his blood is profoundly Christological but is not, by itself, a direct proof of deity, so the record remains Supporting.
Its significance lies in Jesus' extraordinary placement of himself at the center of the covenantal relationship and saving act of God.
The disciples receive the bread and drink from the cup.
