15 Jesus therefore, perceiving that they were about to come and take him by force, to make him king, withdrew again to the mountain by himself.
16 When evening came, his disciples went down to the sea, 17 and they entered into the boat, and were going over the sea to Capernaum. It was now dark, and Jesus had not come to them. 18 The sea was tossed by a great wind blowing. 19 When therefore they had rowed about twenty-five or thirty stadia, [1] they saw Jesus walking on the sea, [2] and drawing near to the boat; and they were afraid. 20 But he said to them, “It is I [3]. Don’t be afraid.” 21 They were willing therefore to receive him into the boat. Immediately the boat was at the land where they were going.
22 On the next day, the multitude that stood on the other side of the sea saw that there was no other boat there, except the one in which his disciples had embarked, and that Jesus hadn’t entered with his disciples into the boat, but his disciples had gone away alone. 23 However boats from Tiberias came near to the place where they ate the bread after the Lord had given thanks. 24 When the multitude therefore saw that Jesus wasn’t there, nor his disciples, they themselves got into the boats, and came to Capernaum, seeking Jesus.

Commentary on John 6:15-21
(Read John 6:15-21)
Here were Christ's disciples in the way of duty, and Christ was praying for them; yet they were in distress. There may be perils and afflictions of this present time, where there is an interest in Christ. Clouds and darkness often surround the children of the light and of the day. They see Jesus walking on the sea. Even the approaches of comfort and deliverance often are so mistaken, as to become the occasions of fear. Nothing is more powerful to convince sinners than that word, "I am Jesus whom thou persecutest;" nothing more powerful to comfort saints than this, "I am Jesus whom thou lovest." If we have received Christ Jesus the Lord, though the night be dark, and the wind high, yet we may comfort ourselves, we shall be at the shore before long.
Commentary on John 6:22-27
(Read John 6:22-27)
Instead of answering the inquiry how he came there, Jesus blamed their asking. The utmost earnestness should be employed in seeking salvation, in the use of appointed means; yet it is to be sought only as the gift of the Son of man. Him the Father has sealed, proved to be God. He declared the Son of man to be the Son of God with power.
