Albert Barnes Commentary John 21:1

"After these things Jesus manifested himself again to the disciples at the sea of Tiberias; and he manifested [himself] on this wise." — John 21:1 (ASV)

The sea of Tiberias. Called also the Sea of Galilee, being situated in Galilee. See Barnes on Matthew 4:18.

In this place Jesus had promised to meet them, Mark 14:28; Mark 16:7; Matthew 26:32; Matthew 28:10.

This interview of Jesus is only briefly mentioned by Matthew (Matthew 28:16), and is omitted by both Mark and Luke. This is the reason why John relates so particularly what occurred there. Galilee was a secluded place where they would be free from danger, and was therefore a safe and convenient situation for Jesus to meet them, in order to give them his last instructions.

On this wise. Thus. In this manner.
