Joshua 2:8 (KJV)

But she had brought them up to the roof of the house, and hid them with the stalks of flax, which she had laid in order upon the roof.

And the men pursued after them the way to Jordan unto the fords: and as soon as they which pursued after them were gone out, they shut the gate.

And before they were laid down, she came up unto them upon the roof;

And she said unto the men, I know that the Lord hath given you the land, and that your terror is fallen upon us, and that all the inhabitants of the land faint because of you.

For we have heard how the Lord dried up the water of the Red sea for you, when ye came out of Egypt; and what ye did unto the two kings of the Amorites, that were on the other side Jordan, Sihon and Og, whom ye utterly destroyed.
