JMNT(i)
34 And so Jesus affirmed to him, "Of a truth (or: Really; Count on it; Amen), I now am saying to you that within this night – before a rooster crows (or: is to crow; other MSS: the crowing of the cock), you will proceed to disown (renounce) Me three times."
35 Peter is then saying to Him, "Even if it should continue necessary for me to die together with You, under no circumstances could (or: would; as a future: will) I disown or renounce You." And all the disciples spoke similarly (or: said likewise).
