Mark 14:13-15

13So 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.

14At 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?’

15He will take you upstairs to a large room that is already set up. That is where you should prepare our meal.”
