Then came the day … on which the Passover lamb had to be sacrificed. So Jesus sent Peter and John, saying, “Go and prepare the Passover for us, that we may eat it.” They said to Him, “Where will You have us prepare it?” He said to them, “Behold, when you have entered the city, a man carrying a jar of water will meet you. Follow him into the house that he enters and tell the master of the house, ‘The Teacher says to you, Where is the guest room, where I may eat the Passover with My disciples?’ And he will show you a large upper room furnished; prepare it there.” (Luke 22:7-12)
