Joshua saved Rahab the prostitute, her family, and all who were with her, because Rahab had helped the men he had sent to spy out Jericho. Rahab still lives among the Israelites today.
Another example is Rahab, a prostitute, who was made right with God by something she did. She welcomed the spies into her home and helped them escape by a different road.
Joshua son of Nun secretly sent out two spies from Acacia and said to them, “Go and look at the land, particularly at the city of Jericho.” So the men went to Jericho and stayed at the house of a prostitute named Rahab.
When we return to this land, you must tie this red rope in the window through which you let us down. Bring your father, mother, brothers, and all your family into your house.
Joshua also put twelve rocks in the middle of the Jordan River where the priests had stood while carrying the Ark of the Agreement. These rocks are still there today.
