Matthew 26:34-35

26:34 Jesus said to him, “I tell you the truth, ¹  on this night, before the rooster crows, you will deny me three times.” 26:35 Peter said to him, “Even if I must die with you, I will never deny you.” And all the disciples said the same thing.

Matthew 26:75

26:75 Then Peter remembered what Jesus had said: “Before the rooster crows, you will deny me three times.” And he went outside and wept bitterly. ² 

Matthew 16:24

16:24 Then Jesus said to his disciples, “If anyone wants to become my follower, ³  he must deny ⁴  himself, take up his cross, ⁵  and follow me.

[26:34]  ¹ tn Grk “Truly (ἀμήν, amhn), I say to you.”

[26:75]  ² sn When Peter went out and wept bitterly it shows he really did not want to fail here and was deeply grieved that he had.

[16:24]  ³ tn Grk “to come after me.”

[16:24]  ⁴ tn This translation better expresses the force of the Greek third person imperative than the traditional “let him deny,” which could be understood as merely permissive.

[16:24]  ⁵ sn To bear the cross means to accept the rejection of the world for turning to Jesus and following him. Discipleship involves a death that is like a crucifixion; see Gal 6:14.
