Mark 14:17-31 New Revised Standard Version (NRSV)
17 When it was evening, he came with the twelve. 18 And when they had taken their places and were eating, Jesus said, “Truly I tell you, one of you will betray me, one who is eating with me.” 19 They began to be distressed and to say to him one after another, “Surely, not I?” 20 He said to them, “It is one of the twelve, one who is dipping bread[a] into the bowl[b] with me. 21 For the Son of Man goes as it is written of him, but woe to that one by whom the Son of Man is betrayed! It would have been better for that one not to have been born.”
The Institution of the Lord’s Supper
22 While they were eating, he took a loaf of bread, and after blessing it he broke it, gave it to them, and said, “Take; this is my body.” 23 Then he took a cup, and after giving thanks he gave it to them, and all of them drank from it. 24 He said to them, “This is my blood of the[c] covenant, which is poured out for many. 25 Truly I tell you, I will never again drink of the fruit of the vine until that day when I drink it new in the kingdom of God.”
Peter’s Denial Foretold
26 When they had sung the hymn, they went out to the Mount of Olives. 27 And Jesus said to them, “You will all become deserters; for it is written,
‘I will strike the shepherd,
28 But after I am raised up, I will go before you to Galilee.” 29 Peter said to him, “Even though all become deserters, I will not.” 30 Jesus said to him, “Truly I tell you, this day, this very night, before the cock crows twice, you will deny me three times.” 31 But he said vehemently, “Even though I must die with you, I will not deny you.” And all of them said the same.
