Mark 14:13-15

13And he sent two of his disciples and said to them, "Go into the city, and a man carrying a jar of water will meet you. Follow him,

14and wherever he enters, say to the master of the house, 'The Teacher says, Where is my guest room, where I may eat the Passover with my disciples?'

15And he will show you a large upper room furnished and ready; there prepare for us."
