Luke 22:12

And he shall show you a large upper room furnished; there make ready.

It had been the custom of the Lord, as a member of the Jewish Church, to celebrate the Passover regularly. When therefore the day came, on the evening of which the Passover meal was held, the disciples came to Jesus with the question whether they should do as they were accustomed to do in the years gone by. Jesus commissioned two of His disciples, Peter and John, to act as His representatives in preparing everything for the meal to be held on that Thursday evening. Upon their inquiry as to the place where they should prepare, He gave them explicit directions. See Matthew 26:17; Mark 14:12. Coming into the city from Bethany, very likely through the Sheep Gate, they would meet a man coming toward them bearing a vessel, a jug, or pitcher, of water; him they should follow to the house into which he would enter. To the master of that house they should make known their wants, asking him for the location of the guest-chamber, the dining-room, where He might eat the Passover-meal with His disciples. The man would thereupon show them an upper room, a flight of stairs up, all furnished with sofas and pillows for such a meal: there they should prepare. The owner of this house is generally assumed to have been a friend, a believer, a disciple of Jesus. Both the authority of Jesus and His divine omniscience are here brought out.
