Cephas - This is a Syriac word, meaning the same as the Greek word Peter, a stone. See the notes at Matthew 16:17. The stone, or rock, is a symbol of firmness and steadiness of character - a trait in Peter’s character after the ascension of Jesus that was very remarkable. before the death of Jesus he was rash, headlong, variable; and it is one proof of the omniscience of Jesus that he saw that Peter “would” possess a character that would be expressed appropriately by the word “stone” or “rock.” The word “Jonas” is a Hebrew word, whose original signification is a “dove.” It may be that Jesus had respect to that when he gave Simon the name Peter. “You now bear a name emblematic of timidity and inconstancy. You shall be called by a name denoting firmness and constancy.”
