Joshua 8:29

He dealt more severely with the kings of Canaan than with the people, partly because the abominable wickedness of that people was not restrained and punished, (as it should have been,) but countenanced and encouraged by their evil examples and administrations; and partly because they were the principal authors of the destruction of their own people, by engaging them in an obstinate opposition against the Israelites. That they should take his carcass down from the tree, according to God's command in that case, Deuteronomy 21:22,23. He chose the entering of the gate of the city, either as most commodious, now especially when all the city within the gate was already turned into a heap of stones and rubbish; or because this was the usual place of judgment, and therefore proper to bear the monument of God's just sentence against him, not without reflection upon that injustice which he had been guilty of in that place.
