Joshua 2:12

so now, swear to me here by God that you will not deal falsely with me or with my offspring or with my posterity, but according to the lovingkindness that I have shown you, you shall show me and the land in which you have sojourned.”

“Only remember me when it goes well with you, and please show me lovingkindness by remembering me to Pharaoh and getting me out of this house.

unless, when we come into the land, you tie this cord of scarlet thread in the window through which you let us down, and gather to yourself into the house your father and your mother and your brothers and all your father’s household.

Now to the two men who had spied out the land, Joshua said, “Go into the harlot’s house and bring the woman and all she has out of there, as you have sworn to her.”

Then the spies saw a man coming out of the city, and they said to him, “Please show us the entrance to the city, and we will treat you with lovingkindness.”

By faith Rahab the harlot did not perish along with those who were disobedient, after welcoming the spies in peace.
