John 1:41-42

"He first found his own brother Simon, and said to him, 'We have found the Messiah' (which is translated, the Christ)."

"And he brought him to Jesus. Now when Jesus looked at him, He said, 'You are Simon the son of Jonah. You shall be called Cephas' (which is translated, a stone)."

(This is Jesus changing Peter's name, for Simon meant weak. Cephas meant a stone, which meant that Jesus was going to make Peter strong.)
