Mark 14:27-31
27 And Jesus said to them, “You will all fall away, for it is written, ‘I will strike the shepherd, and the sheep will be scattered.’ 28 But after I am raised up, I will go before you to Galilee.” 29 Peter said to him, “Even though they all fall away, I will not.” 30 And Jesus said to him, “Truly, I tell you, this very night, before the rooster crows twice, you will deny me three times.” 31 But he said emphatically, “If I must die with you, I will not deny you.” And they all said the same.
