Mark 14:27

24 He said to them, "This is my blood of the new covenant, which is poured out for many.

25 Most assuredly I tell you, I will no more drink of the fruit of the vine, until that day when I drink it anew in the kingdom of God."

26 When they had sung a hymn, they went out to the Mount of Olives.

27 Jesus said to them, "All of you will be made to stumble because of me tonight, for it is written, `I will strike the shepherd, and the sheep will be scattered.`

28 However, after I am raised up, I will go before you into Galilee."

29 But Peter said to him, "Although all will be offended, yet I will not."

30 Jesus said to him, "Most assuredly I tell you, that you today, even this night, before the cock crows twice, you will deny me three times."
