Mark 14:13-15

13And He sent out two of His disciples and said to them, “Go into the city, and a man will meet you carrying a pitcher of water; follow him.

14Wherever he goes in, say to the master of the house, ‘The Teacher says, “Where is the guest room in which I may eat the Passover with My disciples?” ’

15Then he will show you a large upper room, furnished and prepared; there make ready for us.”
