Matthew 16:13-18 (KJV) When Jesus came into the coasts of Caesarea Philippi, he asked his disciples, saying, Whom do men say that I the Son of man am?
And they said, Some say that thou art John the Baptist: some, Elias; and others, Jeremias, or one of the prophets.
He saith unto them, But whom say ye that I am?
And Simon Peter answered and said, Thou art the Christ, the Son of the living God.
And Jesus answered and said unto him, Blessed art thou, Simon Bar-jona: for flesh and blood hath not revealed it unto thee, but my Father which is in heaven.
And I say also unto thee, That thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it.
Peter is a common masculine given name. It is derived from Greek Πέτρος, Petros (an invented, masculine form of Greek petra, the word for “rock” or “stone”), which itself was a translation of Aramaic Kefa (“stone, rock”), the new name Jesus gave to apostle Simon Bar-Jona. An Old English variant is Piers.
