Joshua 8:30

Israel took for themselves only the livestock and the goods of that city, according to the LORD’s word which he commanded Joshua.

So Joshua burned Ai and made it a heap forever, even a desolation, to this day.

He hanged the king of Ai on a tree until the evening. At sundown, Joshua commanded, and they took his body down from the tree and threw it at the entrance of the gate of the city, and raised a great heap of stones on it that remains to this day.

as Moses the servant of the LORD commanded the children of Israel, as it is written in the book of the law of Moses: an altar of uncut stones, on which no one had lifted up any iron. They offered burnt offerings on it to the LORD and sacrificed peace offerings.

He wrote there on the stones a copy of Moses’ law, which he wrote in the presence of the children of Israel.

All Israel, with their elders, officers, and judges, stood on both sides of the ark before the Levitical priests, who carried the ark of the LORD’s covenant, the foreigner as well as the native; half of them in front of Mount Gerizim, and half of them in front of Mount Ebal, as Moses the servant of the LORD had commanded at the first, that they should bless the people of Israel.
