Joshua 6:15-17

On the seventh day the Israelites got up at dawn and marched around the town as they had done before. But this time they went around the town seven times. The seventh time around, as the priests sounded the long blast on their horns, Joshua commanded the people, “Shout! For the LORD has given you the town! Jericho and everything in it must be completely destroyed as an offering to the LORD. Only Rahab the prostitute and the others in her house will be spared, for she protected our spies.
