Mark 14:16

14and wherever he enters in, tell the master of the house, ‘The Teacher says, “Where is the guest room, where I may eat the Passover with my disciples?”’

15He will himself show you a large upper room furnished and ready. Get ready for us there.”

16His disciples went out, and came into the city, and found things as he had said to them, and they prepared the Passover.

17When it was evening he came with the twelve.

18As they sat and were eating, Jesus said, “Most certainly I tell you, one of you will betray me—he who eats with me.”
