Joshua 8:29; Joshua 10:26

29 He hanged the king of Ai on a tree until evening; and at sunset Joshua gave command and they took his body down from the tree and threw it at the entrance of the city gate, and raised over it a great heap of stones that stands to this day.

26 So afterward Joshua struck them and put them to death, and he hanged them on five trees; and they hung on the trees until evening.
