Joshua the son of Nun sent out of Shittim two men as spies secretly, saying, Go, view the land, and Jericho. They went and came into the house of a prostitute whose name was Rahab, and lay there.
The story of Rahab has always intrigued the Christians of every age. Charles H. Spurgeon delivered one of his most memorable sermons on "Rahab."  (For a sermon outline based partially upon Spurgeon's great masterpiece, see Vol. 10 of my N.T. commentary series (Hebrews, under  Hebrews 11:31).)
