Mark 14:13-15

13So he sent two of his disciples, telling them, “Go into the city, and a man carrying a jar of water will meet you. Follow him. 14Say to the owner of the house he enters, ‘The Teacher asks: Where is my guest room, where I may eat the Passover with my disciples?’

15He will show you a large room upstairs, furnished and ready. Make preparations for us there.”
