Church Fathers on John 6:3

As missiles rebound with great force from a hard body, and fly off in all directions, whereas a softer material retains and stops them; so violent men are only excited to greater rage by violence on the side of their opponents, whereas gentleness softens them. Christ quieted the irritation of the Jews by retiring from Jerusalem. He went into Galilee, but not to Cana again, but beyond the sea: After these things Jesus went over the sea of Galilee, which is the sea of Tiberias.

This sea has different names, from the different places with which it is connected; the sea of Galilee, from the province; the sea of Tiberias, from the city of that name. It is called a sea, though it is not salt water, that name being applied to all large pieces of water, in Hebrew. This sea our Lord often passes over, in going to preach to the people bordering on it.

He goes from place to place to try the dispositions of people, and excite a desire to hear Him: And a great multitude followed Him, because they saw His miracles which He did on them that were diseased.
