John 1:40-42 NIV

[40] Andrew, Simon Peter’s brother, was one of the two who heard what John had said and who had followed Jesus. [41] The first thing Andrew did was to find his brother Simon and tell him, “We have found the Messiah” (that is, the Christ). [42] And he brought him to Jesus. Jesus looked at him and said, “You are Simon son of John. You will be called Cephas” (which, when translated, is Peter).
