Mark 14:27-31

And Jesus said to them, You will all fall away this night [that is, you will be caused to stumble and will begin to distrust and desert Me], for it stands written, I will strike the Shepherd, and the sheep will be scattered. [Zech. 13:7.] But after I am raised [to life], I will go before you into Galilee. But Peter said to Him, Even if they all fall away and are caused to stumble and distrust and desert You, yet I will not [do so]! And Jesus said to him, Truly I tell you, this very night, before a cock crows twice, you will utterly deny Me [disclaiming all connection with Me] three times. But [Peter] said more vehemently and repeatedly, [Even] if it should be necessary for me to die with You, I will not deny or disown You! And they all kept saying the same thing.
