Joshua 6:24-26

24And they burned the city with fire, and everything in it. Only the silver and gold, and the vessels of bronze and of iron, they put into the treasury of the house of the Lord.

25But Rahab the prostitute and her father's household and all who belonged to her, Joshua saved alive. And she has lived in Israel to this day, because she hid the messengers whom Joshua sent to spy out Jericho.

26Joshua laid an oath on them at that time, saying, "Cursed before the Lord be the man who rises up and rebuilds this city, Jericho. "At the cost of his firstborn shall he lay its foundation, and at the cost of his youngest son shall he set up its gates."
