And He said to them, “Follow Me, and I will make you fishers of men.” (Matthew 4:19)
Peter and Andrew–Sons of John, were born in Bethsaida. They later settled in a home together in the town of Capernaum. They were fishermen and worked alongside James and John. They were companions and had probably known each other for years.
Peter and Andrew were early followers of John the Baptist. It was Andrew who first introduced his older brother Peter to Jesus when they were in the wilderness with John. (John 1:40-42) It is thought that they became spiritual followers of Jesus at this time. Once Peter was introduced to Jesus they left John and became followers of Christ.
