7 Then came the day of Unleavened Bread on which the Passover lamb had to be sacrificed. 8 Jesus sent Peter and John, saying, “Go and make preparations for us to eat the Passover.”
9 “Where do you want us to prepare for it?” they asked.
10 He replied, “As you enter the city, a man carrying a jar of water will meet you. Follow him to the house that he enters, 11 and say to the owner of the house, ‘The Teacher asks: Where is the guest room, where I may eat the Passover with my disciples?’ 12 He will show you a large room upstairs, all furnished. Make preparations there.”
13 They left and found things just as Jesus had told them. So they prepared the Passover.
