Mark 14:30-31

Jesus said to him, “I assure you and most solemnly say to you, this very night, before a rooster crows twice, you will deny [that you even know] Me three times.” [Matt 26:34; John 13:38] But Peter kept saying insistently, “If I have to die with You, I will not deny You!” And they all were saying the same thing as well.
