And to Simon he gave the name Peter:

“(de Con. Evan. ii. 17) But let no one suppose that Simon now received his name and was called Peter, for thus he would make Mark contrary to John, who relates that it had been long before said unto him, Thou shalt be called Cephas. (John 1:42) But Mark gives this account by way of recapitulation; for as he wished to give the names of the twelve Apostles, and was obliged to call him Peter, his object was to intimate briefly, that he was not called this originally, but that the Lord gave him that name.”

“(ubi sup.) And the reason that the Lord willed that he should at first be called otherwise, was that from the change itself of the name, a mystery might be conveyed to us. Peter then in Latin or in Greek means the same thing as Cephas in Hebrew, and in each language the name is drawn from a stone. Nor can it be doubted that is the rock of which Paul spoke, And this rock was Christ. (1 Cor. 10:4) For as Christ was the true light, and allowed also that the Apostles should be called the light of the world, (Matt. 5:14.) so also to Simon, who believed on the rock Christ, He gave the name of Rock.”

“And Simon he surnamed Peter. Or Cephas, which signifies a rock, or stone, because of his courage and constancy, his strength and fortitude, steadiness and firmness of mind: this name was imposed upon him, not at the time of his mission as an apostle; nor when he made that noble confession of his faith in Christ, as the Son of the living God, at which time this name was taken notice of; but when Christ first called him to be his disciple and apostle; see Joh 1:42. . Mark 3:17 mar 3:17 mar 3:17 mar 3:17And James the son of Zebedee, and John the brother of James,.... These are mentioned next, as being first called after Peter and Andrew: and he surnamed them Boanerges, which is, the sons of thunder: either because of their loud and sonorous voice; or their warm zeal for Christ, and fervency in their ministry: or for their courage in opposing the enemies of Christ, and the power that went along with their words; which either put to confusion and silence, or issued in conviction and conversion. The Syriac version reads, "Benai Regesh", and the Persic, "Beni Reg'sch". The Jews, as our learned countryman Mr. Broughton has observed (w), sometimes pronounce "Scheva" by on, as Noabyim", for "Nebyim"; so here, "Boanerges" for Benereges", or "Benerges". There is a city which was in the tribe of Dan, mentioned in Jos 19:45, which is called "Bene-berak, the sons of lightning"; and is spoken of in the Jewish (x) writings, as a place where several of the Rabbins met, and conversed together: the reason of this name may be inquired after.

“The evangelist here gives the names of the twelve. First, Simon, to whom he gave the name of Peter, in Greek, Petron , which signifies a rock; thus shewing that upon him his Church should be founded, as on a rock, never to be overturned. (Tirinus) — Polus, in his Synopsis Criticorum on this verse says that some Greek copies have, Proton Simona , First, Simon, which he believes to be the genuine reading: “nec dubito quin hæc sit germana lectio.””
