Matthew 26:31

28 for this is my blood of the new covenant, that for many is being poured out -- to remission of sins;

29 and I say to you, that I may not drink henceforth on this produce of the vine, till that day when I may drink it with you new in the reign of my Father.`

30 And having sung a hymn, they went forth to the mount of the Olives;

31 then saith Jesus to them, `All ye shall be stumbled at me this night; for it hath been written, I will smite the shepherd, and the sheep of the flock shall be scattered abroad;

32 but, after my having risen, I will go before you to Galilee.`

33 And Peter answering said to him, `Even if all shall be stumbled at thee, I will never be stumbled.`

34 Jesus said to him, `Verily I say to thee, that, this night, before cock-crowing, thrice thou wilt deny me.`
