Albert Barnes Commentary John 6:1

"After these things Jesus went away to the other side of the sea of Galilee, which is [the sea] of Tiberias." — John 6:1 (ASV)

Jesus went over. Went to the east side of the sea. The place to which he went was Bethsaida, Luke 9:10. The account of this miracle of feeding the five thousand is recorded also in Matthew 14:13-21, Mark 6:32–44, and Luke 9:10-17. John has added a few circumstances omitted by the other evangelists.
