SO MANY inaccuracies, which is impressive because the author is going by the plain meaning of the text. But the writing itself is not bad, so I give it 2 stars. An example of the inaccuracies: he states that 2.5 of the tribes (and even names them) are going to leave their wives, children, and animals on the desert-side of the Jordan river. Ok, that's right. He says it's to put them in the mood to fight? HUH? The women, children, and animals of the 9.5 other tribes (or 10.5, depending on how you count them) are with them. So it's obviously not to help them fight. It's straight in the text that those 2.5 tribes asked to have their portion of land be on the "wrong" side of the Jordan River. This is a huge deal, so Joshua has to ask Gd whether they can do that. Gd gives permission, and that is why the women, children, and animals are left behind. They have been given homes. The others still have to fight for their homes and don't have anywhere to leave those "inconvenient for war" people and animals. Later, he comes back to this when they're crossing the Jordan River, and is all surprised that "all the people of Israel cross" so that means even the women and children are with them! That is assuming that the women and children left behind came with the tribes instead, and they didn't. They remained home on the other side of the Jordan. But yes, there were women and children because, as I said before, those women and children weren't left behind in the first place. UGH.
Also? Achan's family. It's not clear whether his family was executed or not. Maybe they were called to escort him. Or maybe they were killed with him. The text doesn't say. I'm willing to give the author a little more leeway on this one, but still reading what he wants to read.
Those were my 2 pet peeves.
