One of the two who heard John speak and followed Jesus was Andrew, Simon Peter’s brother. John:1:40 ESV
According to Christian tradition, Andrew was born at Bethsaida (Greek: Βηθσαϊδά Bēthsaïda "house or place of hunting or fishing" of Aramaic origin בַּיִת צַיָּד bayith "house" tsayad "hunter"), a small fishing village on the west shore of Lake Gennesaret Sea of Galilee, home of Andrew, Peter, Philip and John (John 1:44). Since he was a Jew, Andreas was almost certainly not his given name, but no Hebrew or Aramaic name is recorded for him. He had been a disciple of John the Baptist (John 1:37-40) and was one of the first to follow Jesus. He lived at Capernaum (Mark 1:29). In the gospels he is referred to as being present on some important occasions as one of the disciples more closely attached to Jesus (Mark 13:3; John 6:8, 12:22). In the book of Matthew, Jesus said, to Andrew and his brother Simon, "Follow me, and I will make you fishers of men." (Greek: ἁλιεύς ἄνθρωπος halieus "a fisherman, fisher" anthrōpos "a human being, whether male or female") in Acts there is only a bare mention of him (Acts 1:13).
