Matthew 26:33-35 ESV
Peter answered him, “Though they all fall away because of you, I will never fall away.” Jesus said to him, “Truly, I tell you, this very night, before the rooster crows, you will deny me three times.” Peter said to him, “Even if I must die with you, I will not deny you!” And all the disciples said the same.
