15 On the seventh day they rose early, at the dawn of day, and marched around the city in the same manner seven times. It was only on that day that they marched around the city seven times. 16 And at the seventh time, when the priests had blown the trumpets, Joshua said to the people, “Shout, for the Lord has given you the city. 17 And the city and all that is within it shall be devoted to the Lord for destruction.  Only Rahab the prostitute and all who are with her in her house shall live, because she hid the messengers whom we sent. 18 But you, keep yourselves from the things devoted to destruction, lest when you have devoted them you take any of the devoted things and make the camp of Israel a thing for destruction and bring trouble upon it. 19 But all silver and gold, and every vessel of bronze and iron, are holy to the Lord; they shall go into the treasury of the Lord.” 20 So the people shouted, and the trumpets were blown. As soon as the people heard the sound of the trumpet, the people shouted a great shout, and the wall fell down flat, so that the people went up into the city, every man straight before him, and they captured the city. 21 Then they devoted all in the city to destruction, both men and women, young and old, oxen, sheep, and donkeys, with the edge of the sword.
22 But to the two men who had spied out the land, Joshua said, “Go into the prostitute's house and bring out from there the woman and all who belong to her, as you swore to her.” 23 So the young men who had been spies went in and brought out Rahab and her father and mother and brothers and all who belonged to her. And they brought all her relatives and put them outside the camp of Israel. 24 And 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. 25 But 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.
26 Joshua 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.”
27 So the Lord was with Joshua, and his fame was in all the land. (ESV)
