Joshua 2:18

Behold, when we come into the land, thou shall bind this line of scarlet thread, a thin, but strong rope, such as surveyors used, probably the one by which they had made their escape, 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, who apparently were living in their own homes, home unto thee, thus having them all together in one house.
