Joshua 2:9-12

9and said to them, “I know that the LORD has given you this land and that a great fear of you has fallen on us, so that all who live in this country are melting in fear because of you. 10We have heard how the LORD dried up the water of the Red Sea Or the Sea of Reeds for you when you came out of Egypt, and what you did to Sihon and Og, the two kings of the Amorites east of the Jordan, whom you completely destroyed. The Hebrew term refers to the irrevocable giving over of things or persons to the Lord, often by totally destroying them.

11When we heard of it, our hearts melted in fear and everyone’s courage failed because of you, for the LORD your God is God in heaven above and on the earth below. 12“Now then, please swear to me by the LORD that you will show kindness to my family, because I have shown kindness to you. Give me a sure sign
