‘And after these things Jesus walked in Galilee, for he would not walk in Judea because the Judaisers sought to kill him.'
‘After these things'. A loose connecting phrase indicating a change of narrative and having little other significance except to link with, and probably date it later than, the previous chapter.
His words to the Judaisers in chapter 6 had increased their determination to put Him to death. But they did not dare to touch Him in Galilee, where their influence was less, for He was too popular, and the result was that He was able to walk openly there. This very fact confirms that a wide Galilean ministry is assumed, but not touched on, in John's Gospel.
So they decided that they would wait for Him to come to Judea. It would appear from this situation that the end of His ministry was now approaching demonstrating that John had mainly left the details of His earlier ministry to others. From now on there will be constant references to their planning of His death (see John 7:19; John 7:30; John 7:32; John 7:44; John 8:59; John 10:39; John 11:8; John 11:53).
