Now that I have gotten over the shock of the fact that the lectionary skips over almost the entire Book of Joshua, I can make a few comments on the reading for today (Jos. 24.1-13). Here we have Joshua functioning like a prophet. We found out in Deut. 34.10 that Moses was a prophet. A lot of what Joshua does mirrors what Moses did, e.g. miraculously leading the people through water (Jos. 3), having an encounter where he must remove his sandals (Jos. 5.15), etc. So, we should not be surprised to see Joshua functioning like a prophet.
