Joshua, and all Israel with him, took Achan the son of Zerah, and the silver, and the mantle, and the wedge of gold, and his sons, and his daughters, and his oxen, and his donkeys, and his sheep, and his tent, and all that he had: and they brought them up to the valley of Achor.
Chapters 1-7 form a unit of text: the Jericho siege narrative. Rahab and Achan open and close this section respectively forming its "bookends." Rahab was a female Canaanite prostitute; Achan was an Israelite man. Rahab hid the spies under her roof; Achan hid stolen loot under his tent. Rahab, her house, and her family were saved; Achan, his tent, and his family were destroyed. The writer was teaching theology by the way he constructed his narrative. [Note: J.
