‘ As YHWH commanded Moses his servant, so did Moses command Joshua, and so Joshua did. He left nothing undone of all that YHWH had commanded Moses.'
Joshua's complete obedience is emphasised. He was fulfilling the work of God through Moses. He stood in Moses' place. And he was faithful in his service. That is why in the end he would be given the honourable title ‘the Servant of YHWH' (Joshua 24:29; Judges 2:8), a unique title only specifically given by the people to Moses and Joshua.
So Joshua's northern campaign came to an end. We should, however, note what is not said. There is no suggestion that he captured Megiddo or Taanach, the two great cities on either side of the plain of Esdraelon, (although he would kill their kings - Joshua 12:21 - so that they clearly acted aggressively against Israel) nor does it say that he captured Jerusalem or Bethel or Gezer. Nor is there any mention of capturing the cities of Gath, Ashkelon, Ekron, Ashdod and Gaza (Joshua 10:41 does not say that Gaza was taken). And there were other great cities also unmentioned. The impression of overall victory has within it important silences. The record is honest about the non-capture of the coastal plain and Esdraelon, and other heavily defended cities. And it makes clear that in spite of the great victories that were obtained the cities were not occupied at this stage. His work was only the beginning, with the purpose of establishing Israel in the land. Others would have to follow it up and make the victories permanent. And this they failed to do as we know from Judges 1. But its overall message is that he was successful wherever he went, and that YHWH was with him.
