John Gill Bible Commentary

Peter answered and said unto him,.... Who was always a forward man, free to speak his mind, and was often the mouth of the rest; observing what Christ had affirmed concerning all of them, that that very night, in a very short space of time, they would be offended because of him; and knowing the strong love he had for Christ, and being persuaded it could never be his case, thus addresses him, though all men shall be offended because of thee, yet will I never be offended: his sense is, that though all the men in the world, friends, and foes, though even all the rest of the disciples, who were his most intimate friends, most closely attached to him, and who dearly loved him, and sincerely believed in him, should be so stumbled at what should befall him, as to flee from him, and be tempted to relinquish his cause, and interest; yet nothing should ever cause him, in the least, to stumble and fall, to desert him, or hesitate about him, or cause him to take the least umbrage and offence at what might come upon him; and this he was positive of would be the case, not only that night, but ever after. No doubt he said this in the sincerity of his heart, and out of his great fervour of affection for Christ; but what he failed in, was trusting to his own strength, being self-confident; and in entertaining greater opinion of himself, and his steady attachment to Christ, than of the rest of the disciples; and in contradicting what Christ had so strongly affirmed of them all, without any exception, and so of himself, and had confirmed by so glaring a prophecy concerning this matter.
