Mark 14:12-21  NAS

On the first day of Unleavened Bread, when the Passover lamb was being sacrificed, His disciples said to Him, "Where do You want us to go and prepare for You to eat this Passover?"  And He sent two of His disciples and said to them, "Go into the city, and a man will meet you carrying a pitcher of water; follow him; and wherever he enters say to owner of the house, 'The Teacher says, "Where is My guest room in which I may eat the Passover with My disciples?" ' And he will show you a large upper room furnished and ready; prepare for us There."  The disciples went out and came to the city, and found it just as He had told them; and they prepared the Passover.

When it was evening He came with the twelve.  As they were reclining at the table and eating, Jesus said, "Truly I say to you that one of you will betray Me--one who is eating with Me."  They began to be grieved and to say to Him one by one, "Surely not I?"  And He said to them, "It is one of the twelve, one who dips with Me in the bowl.  For the Son of Man is to go just as it is written of Him; but woe to that man by whom the Son of Man is betrayed!  It would have been good for that man if he had not been born."
