Matthew 26:19

Made ready the passover. The preparation probably included the following: searching the room for leaven, sweeping the room, and furnishing it with a table, couches or cushions, and the utensils needed for serving the meal. Though Inspiration says nothing specifically of a lamb in connection with the supper Jesus ate with His disciples, it seems doubtful that they would have celebrated the paschal meal without one (see Mark 14:12, 16, 17, 18; Luke 22:7, 8, 13-15). Accordingly, Peter and John would purchase a lamb, slay it, and roast it. They would also prepare unleavened bread, bitter herbs, sauce, and wine. These preparations doubtless occupied a considerable part of the day, and it was probably toward evening when Peter and John returned.
