We follow them from the house of the goodman toward the Temple. Nearing it they listen with mournful solemnity to the chanting of the eighty-first Psalm, with its exhortation to praise,—"Sing aloud unto God our strength. Blow up the trumpet in the new moon, in the time appointed, on the solemn feast day." Then they listen for the threefold blast of the silver trumpets. By this they know that the hour has come for the slaying of the lambs. Peter and John enter the court of the priests, and slay their lamb whose blood is caught by a priest in a golden bowl, and carried to the Great Altar.
Of this they must have been reminded a few hours later when Christ spoke of His own blood shed for the remission of sins. John must have remembered it when he saw and wrote of the "blood and water" that flowed from the pierced side of his Lord. While the lamb is being slain the priests are chanting, and the people responding, "Hallelujah: Blessed is He that cometh in the Name of the Lord."
The lamb of sacrifice, slain and cleansed and roasted, is carried by the two disciples on staves to the upper room. After lighting the festive lamps, they have obeyed their Lord's command, "Make ready the Passover."
Meanwhile He and the remaining ten, as the sun is setting, descend the Mount of Olives, from which He takes His last view of the holy but fated city. The disciples follow Him, still awed by what He had told them of its fate, and with forebodings of what awaited Him and them. Among them was the traitor carrying his terrible secret, bent on its awful purpose which is unknown to the nine, but well known to the Master. Thus they go to the upper room where Peter and John are ready to receive them.
In Jesus' message to the goodman He said, "I will keep the Passover at thy house with My disciples." They were His family. He chose to be alone with them. Not even the mothers Mary and Salome, nor Nicodemus on this night, nor the family of Bethany, could be of His company. No Mary was here to anoint His feet with ointment; nor woman who had been a sinner to bathe them with her tears. Lazarus was not one of them that sat with them; nor did "Martha serve." It was the twelve whom He had chosen, and who had continued with Him. It was to His apostolic family that He said, "With desire I have desired to eat this Passover with you before I suffer." And so "He sat down with the twelve" alone, the only time—as is supposed—that He ever ate the Passover meal with His disciples.
That room became of special interest to John. Sent by his Master to find it, he was mysteriously guided thither. There he was welcomed by the good owner of the house, who united with him in preparation for the most memorable feast ever held. It is there that we see him in closest companionship with his Lord. It was the place in Jesus' mind when He said, "Go and make ready for us the Passover." "Where shall we go?" asked John. He found answer when he entered that upper room. Because of his relation thereto it has been called "St. John's Room"—more sacred than any "Jerusalem Chamber," so named, or any "St. John's Cathedral!"
