‘And early in the morning he came again into the Temple, and all the people came to him, and he sat down and taught them.'
Thus it is that early in morning He is again in the Temple ready to teach the people. So in spite of the constant danger of arrest, next morning He is seen as having gone to the Temple where He ‘sits down' to teach the people who have gathered to Him. There are many who are still concerned to hear Him and He will not leave them as sheep without a shepherd. Sitting to teach in the Temple was commonplace for Rabbis, and their disciples would gather round to listen to their words, which were also open to any in the crowds who were interested. Anyone could ask questions (compare Luke 2:46).
In view of the previous chapter and the following reference to the light of the world (John 8:12) it may be that ‘early in the morning' here is to be seen as significant. As a Galilean He has come to bring men from darkness into day in accordance with the words of Isaiah in Isaiah 9:1-2, where ‘Galilee of the nations' is made glorious in the fact that ‘the people that walked in darkness have seen a great light'. Thus it may be being suggested that the early light was not for those who were of the Judean religious establishment, but were for the poor and the meek and the spiritual.
It is interesting to note that this passage in Isaiah does not appear to have occurred to any of the Pharisees in their religious deliberations. They were simply not interested in any promises connected with Galilee.
