John 6: 1

[Thirdwoe]

The parallel passage in Mark 6:30-34 doesn't use the term "crossing" other than referring to the place they were headed to in the ship/boat as a desert or wilderness region. And when you read it, it seems that it was a fairly short trip to where they were going, and seems that it wasn't all the way across the see of Galilee's middle, but rather up or down the coast line a ways. Notice the wording there in Mark where the people on land noticed what direction they were going and ran along the shore line and arrived there ahead of them.
