Joshua 2:18 YLT

¹⁶  and she saith to them, 'To the mountain go, lest the pursuers come upon you; and ye have been hidden there three days till the turning back of the pursuers, and afterwards ye go on your way.'

¹⁷  And the men say unto her, 'We are acquitted of this thine oath which thou hast caused us to swear:

¹⁸  lo, we are coming into the land, this line of scarlet thread thou dost bind to the window by which thou hast caused us to go down, and thy father, and thy mother, and thy brethren, and all the house of thy father thou dost gather unto thee, to the house;

¹⁹  and it hath been, any one who goeth out from the doors of thy house without, his blood 'is' on his head, and we are innocent; and any one who is with thee in the house, his blood 'is' on our head, if a hand is on him;

²⁰  and if thou declare this our matter, then we have been acquitted from thine oath which thou hast caused us to swear.'
