Joshua 6:25-26

25And Joshua spared Rahab the harlot, her father’s household, and all that she had. So she dwells in Israel to this day, because she hid the messengers whom Joshua sent to spy out Jericho.

26Then Joshua charged them at that time, saying, “Cursed be the man before the Lord who rises up and builds this city Jericho; he shall lay its foundation with his firstborn, and with his youngest he shall set up its gates.”
