John 6:22
On the next day the crowd that had stayed on the other [i.e., east] side of the lake realized that there had been only one boat there. They [also] knew that Jesus was not aboard the boat when it left with the disciples in it, but that they had left without Him.
Matthew 14:22
Then immediately Jesus ordered the disciples to enter the boat and row on ahead of Him to the other side [i.e., to the west side of Lake Galilee] until He could send the crowds away.
Mark 6:45
And about then Jesus compelled His disciples to get into a boat and go on ahead of Him to the other side [i.e., to the west side of Lake Galilee] to Bethsaida [Note: This was apparently a different "Bethsaida" from the one mentioned in Luke 9:10, which was on the east side of Lake Galilee], while He Himself sent the crowd away.
John 6:2
And a large crowd followed Him because they had seen the [miraculous] signs He had performed on sick people.
John 6:15-21
So, [when] Jesus knew that the people were about to come and forcibly take Him and make Him [their] king, He left there again and went to the high plateau [to be] alone [i.e., to pray. See Mark 6:46].
