Mark 14:13-16

So Jesus sent two of them into Jerusalem with these instructions: “As you go into the city, a man carrying a pitcher of water will meet you. Follow him. At the house he enters, say to the owner, ‘The Teacher asks: Where is the guest room where I can eat the Passover meal with my disciples?’ He will take you upstairs to a large room that is already set up. That is where you should prepare our meal.” So the two disciples went into the city and found everything just as Jesus had said, and they prepared the Passover meal there.
