John 6:15

6:15 Then Jesus, because he knew they were going to come and seize him by force to make him king, withdrew again up the mountainside alone. ¹ 

John 6:64

6:64 But there are some of you who do not believe.” (For Jesus had already known from the beginning who those were who did not believe, and who it was who would betray him.) ² 

[6:15]  ¹ sn Jesus, knowing that his “hour” had not yet come (and would not, in this fashion) withdrew again up the mountainside alone. The ministry of miracles in Galilee, ending with this, the multiplication of the bread (the last public miracle in Galilee recorded by John) aroused such a popular response that there was danger of an uprising. This would have given the authorities a legal excuse to arrest Jesus. The nature of Jesus’ kingship will become an issue again in the passion narrative of the Fourth Gospel (John 18:33ff.). Furthermore, the volatile reaction of the Galileans to the signs prepares for and foreshadows the misunderstanding of the miracle itself, and even the misunderstanding of Jesus’ explanation of it (John 6:22-71).
