Joshua 2:10-14

For we have heard how the Lord dried up the water of the Red Sea before you when you came out of Egypt, and what you did to the two kings of the Amorites who were beyond the Jordan, to Sihon and Og, whom you utterly destroyed.

When we heard these reports, our hearts melted and no courage remained in anyone any longer because of you; for the Lord your God, He is God in heaven above and on earth below.

Now then, please swear to me by the Lord, since I have dealt kindly with you, that you also will deal kindly with my father’s household, and give me a pledge of truth,

and spare my father and my mother, and my brothers and my sisters, and all who belong to them, and save our lives from death.”

So the men said to her, “Our life for yours if you do not tell this business of ours; and it shall come about when the Lord gives us the land that we will deal kindly and faithfully with you.” The Promise to Rahab
