Now what is here said concerning the foregoing denial of Peter is contained in all the Evangelists, but they do not all happen to relate it upon the same occasion in the discourse. Matthew and Mark subjoin it after our Lord had departed from the house where He had eaten the Passover, but Luke and John before He went out from thence. But we may easily understand either that the two former used these words, recapitulating them, or the two others anticipating them: only it rather moves us, that not only the words but even the sentences of our Lord, in which Peter being troubled used that boast of dying either for or with our Lord, are given so differently, as rather to compel us to believe that he thrice uttered his boast at different parts of our Lord’s discourse, and that he was thrice answered by our Lord, that before the cock crowed he should deny Him thrice.
