This might be related to Isaiah 53:12 in his description of the suffering servant. The original covenant was a blood sacrifice Moses made to God to seal God's deal with the Israelites before Moses went up to receive the Ten Commandments in Exodus 24:8. Blood was a symbol of life in the Jewish culture. (Kilgallen 267) Jesus does not state that the bread and wine are "like" him, but "are" his body and blood. Jesus is asking his disciples to take part in his sacrificial death. (Brown "et al." 626) (See also Transubstantiation) Mark uses the term "hyper pollōn" (for many), based on the Hebrew of Isaiah 53:12 with "many" being all people, not just the disciples (Brown "et al." 626). This episode in contrasted with the predictions of his betrayal and Peter's denial's, showing the sacrificial nature of his offering. Taking Jesus' body as food shows him as sustainer and a source of strength. (Kilgallen 266) (See also ) They then sing a hymn, "in all probability the concluding portion of the Hallel", and leave and return to the Mount of Olives. The singing of hymns on Passover was a way of giving thanks. (Kilgallen 268) According to Luke, Jesus told everyone to take a purse, a bag, and two swords with them (see also But to bring a sword).
