34 He called the crowd with his disciples, and said to them, “If any want to become my followers, let them deny themselves and take up their cross and follow me. 35 For those who want to save their life will lose it, and those who lose their life for my sake, and for the sake of the gospel,[i] will save it.
Mark 14:26-31; 66-72
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,
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 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.
66 While Peter was below in the courtyard, one of the servant-girls of the high priest came by. 67 When she saw Peter warming himself, she stared at him and said, “You also were with Jesus, the man from Nazareth.” 68 But he denied it, saying, “I do not know or understand what you are talking about.” And he went out into the forecourt.[k] Then the cock crowed.[l] 69 And the servant-girl, on seeing him, began again to say to the bystanders, “This man is one of them.” 70 But again he denied it. Then after a little while the bystanders again said to Peter, “Certainly you are one of them; for you are a Galilean.” 71 But he began to curse, and he swore an oath, “I do not know this man you are talking about.” 72 At that moment the cock crowed for the second time. Then Peter remembered that Jesus had said to him, “Before the cock crows twice, you will deny me three times.” And he broke down and wept.
