Luke 22:10-12

10And He said to them, “Behold, when you have entered the city, a man will meet you carrying a pitcher of water; follow him into the house which he enters.

11Then you shall say to the master of the house, ‘The Teacher says to you, “Where is the guest room where I may eat the Passover with My disciples?” ’

12Then he will show you a large, furnished upper room; there make ready.”
