But Peter said to Him, "[Even] though all may fall away, yet I will not."
But Peter said unto him, Although all shall be offended, yet will not I.
But Peter said to Him, Even if they all fall away and are caused to stumble and distrust and desert You, yet I will not [do so]!
Peter said to him, “Even if everyone else stumbles, I won’t.”
Then Peter said to him, "Even if all will have fallen away from you, yet I will not."
