Nisan 12 and 13
Jesus spends Nisan 12 quietly with his disciples. He realizes that the religious leaders desperately want to kill him, and he does not want them to hinder his Passover celebration the following evening. (Mark 14:1, 2) The next day, Nisan 13, people are busy making final arrangements for the Passover. Early in the afternoon, Jesus sends Peter and John to prepare the Passover for them in an upper room in Jerusalem. (Mark 14:12-16; Luke 22:8) A little before sundown, Jesus and the other ten apostles meet them there for their last Passover celebration.
