Joshua 9:15

When thou comest nigh unto a city to fight against it, then proclaim peace unto it.

Now therefore, I pray you, swear unto me by the LORD, since I have showed you kindness, that ye will also show kindness unto my father's house, and give me a true token: And that ye will save alive my father, and my mother, and my brethren, and my sisters, and all that they have, and deliver our lives from death. And the men answered her, Our life for yours, if ye utter not this our business. And it shall be, when the LORD hath given us the land, that we will deal kindly and truly with thee. Then she let them down by a cord through the window: for her house was upon the town wall, and she dwelt upon the wall. And she said unto them, Get you to the mountain, lest the pursuers meet you; and hide yourselves there three days, until the pursuers be returned: and afterward may ye go your way. And the men said unto her, We will be blameless of this thine oath which thou hast made us swear. Behold, when we come into the land, thou shalt bind this line of scarlet thread in the window which thou didst let us down by: and thou shalt bring thy father, and thy mother, and thy brethren, and all thy father's household, home unto thee. And it shall be, that whosoever shall go out of the doors of thy house into the street, his blood shall be upon his head, and we will be guiltless: and whosoever shall be with thee in the house, his blood shall be on our head, if any hand be upon him.

But Joshua had said unto the two men that had spied out the country, Go into the harlot's house, and bring out thence the woman, and all that she hath, as ye sware unto her. And the young men that were spies went in, and brought out Rahab, and her father, and her mother, and her brethren, and all that she had; and they brought out all her kindred, and left them without the camp of Israel. And they burnt the city with fire, and all that was therein: only the silver, and the gold, and the vessels of brass and of iron, they put into the treasury of the house of the LORD. And Joshua saved Rahab the harlot alive, and her father's household, and all that she had; and she dwelleth in Israel even unto this day; because she hid the messengers, which Joshua sent to spy out Jericho.

There was not a city that made peace with the children of Israel, save the Hivites the inhabitants of Gibeon: all other they took in battle.

And the king called the Gibeonites, and said unto them; (now the Gibeonites were not of the children of Israel, but of the remnant of the Amorites; and the children of Israel had sworn unto them: and Saul sought to slay them in his zeal to the children of Israel and Judah.)

At what instant I shall speak concerning a nation, and concerning a kingdom, to pluck up, and to pull down, and to destroy it;
