Mark 14:13-15

13And he sends two of his disciples, and says to them, Go into the city, and a man shall meet you carrying a pitcher of water; follow him.

14And wheresoever he enters, say to the master of the house, The Teacher says, Where is my guest-chamber where I may eat the passover with my disciples?

15and he will shew you a large upper room furnished ready. There make ready for us.
