John 1:40-44

1:40 One of the two which heard John [speak], and followed him, was Andrew, Simon Peter’s brother. 1:41 He first findeth his own brother Simon, and saith unto him, We have found the Messias, which is, being interpreted, the Christ. 1:42 And he brought him to Jesus. And when Jesus beheld him, he said, Thou art Simon the son of Jona: thou shalt be called Cephas, which is by interpretation, A stone. 1:43 The day following Jesus would go forth into Galilee, and findeth Philip, and saith unto him, Follow me. 1:44 Now Philip was of Bethsaida, the city of Andrew and Peter.

Matthew 4:18

4:18 And Jesus, walking by the sea of Galilee, saw two brethren, Simon called Peter, and Andrew his brother, casting a net into the sea: for they were fishers.
