Joshua 6:25-26

25However, 1Rahab the harlot and her father’s household and all she had, Joshua 2spared; and she has lived in the midst of Israel to this day, for 3she hid the messengers whom Joshua sent to spy out Jericho.

26Then Joshua made them take an oath at that time, saying, “4Cursed before the Lord is the man who rises up and builds this city Jericho; with the loss of his firstborn he shall lay its foundation, and with the loss of his youngest son he shall set up its gates.”
