29 and the king of Ai he hath hanged on the tree till even-time, and at the going in of the sun hath Joshua commanded, and they take down his carcase from the tree, and cast it unto the opening of the gate of the city, and raise over it a great heap of stones till this day.
Matthew Henry's Commentary on Joshua 8:29
Commentary on Joshua 8:23-29
(Read Joshua 8:23-29)
God, the righteous Judge, had sentenced the Canaanites for their wickedness; the Israelites only executed his doom. None of their conduct can be drawn into an example for others. Especial reason no doubt there was for this severity to the king of Ai; it is likely he had been notoriously wicked and vile, and a blasphemer of the God of Israel.
