Then Jesus sent two of them with these instructions: "Go into the city, and a man carrying a jar of water will meet you. Follow him
to the house he enters, and say to the owner of the house: "The Teacher says, Where is the room where my disciples and I will eat the Passover meal?'
Then he will show you a large upstairs room, fixed up and furnished, where you will get everything ready for us."
The disciples left, went to the city, and found everything just as Jesus had told them; and they prepared the Passover meal.
When it was evening, Jesus came with the twelve disciples.
While they were at the table eating, Jesus said, "I tell you that one of you will betray me - one who is eating with me." 1
