John 6:15

departed . . . to a mountain himself alone--(1) to rest, which He came to this "desert place" on purpose to do before the miracle of the loaves, but could not for the multitude that followed Him (see Mar 6:31); and (2) "to pray" (Mat 14:23; Mar 6:46). But from His mountain-top He kept watching the ship (see on Joh 6:18), and doubtless prayed both for them, and with a view to the new manifestation which He was to give them of His glory.

Here is, I. Christ's retirement from the multitude. 1. Observe what induced him to retire; because he perceived that those who acknowledged him to be that prophet that should come into the world would come, and take him by force, to make him a king, Joh 6:15. Now here we have an instance, (1.) Of the irregular zeal of some of Christ's followers; nothing would serve but they would make him a king. Now, [1.] This was an act of zeal for the honour of Christ, and against the contempt which the ruling part of the Jewish church put upon him. They were concerned to see so great a benefactor to the world so little esteemed in it; and therefore, since royal titles are counted the most illustrious, they would make him a king, knowing that the Messiah was to be a king; and if a prophet, like Moses, then a sovereign prince and lawgiver, like him; and, if they cannot set him up upon the holy hill of Zion, a mountain in Galilee shall serve for the present. Those whom Christ has feasted with the royal dainties of heaven should, in return for his favour, make him their king, and set him upon the throne in their souls: let him that has fed us rule us. But, [2.] It was an irregular zeal; for First, It was grounded upon a mistake concerning the nature of Christ's kingdom, as if it were to be of this world, and he must appear with outward pomp, a crown on his head, and an army at his foot; such a king as this they would make him, which was as great a disparagement to his glory as it would be to lacquer gold or paint a ruby. Right notions of Christ's kingdom would keep us to right methods for advancing it. Secondly, It was excited by the love of the flesh; they would make him their king who could feed them so plentifully without their toil, and save them from the curse of eating their bread…

6:15 The people were ready to force Jesus to become their king. To avoid this role, Jesus fled the crowd and commanded his disciples to go back across the lake (Mark 6:45-46).
