Joshua 5:13-15 recounts when Joshua stands (then bows) before the commander of the Lord's army and then is told to take off his sandals- since that is the end of the recorded conversation:
a) is that all the commander told him? Or b) does the conversation continue unrecorded? Or c) does the conversation spill on into chapter 6 where G-d (and not the commander) is identified as telling Joshua that he has handed Jericho over to him?
If a), then why would that be all that was said? If b), then what could have been the conversation? Perhaps Joshua is having his "burning bush" experience and is being given specific instructions as Moses was? If so, then why would Joshua's conversation be unrecorded where Moses' was written down? If c), then why the change in identifiers from "the commander..." to "G-d"?
