'Scouts' in the Bible

So Moses sent spies from the Wilderness of Paran at the command of the Lord, all of them men who were heads of the Israelites.

But the men who had gone up with him said, “We are not able to go up against the people [of Canaan], for they are too strong for us.”

Joshua the son of Nun and Caleb the son of Jephunneh, who were among those who had spied out the land, tore their clothes [as a sign of grief],

and they spoke to all the congregation of the sons of Israel, saying, “The land through which we passed as spies is an exceedingly good land.

Joshua the son of Nun sent two men as scouts secretly from Shittim, saying, “Go, view the land, especially Jericho [the walled city].” So they went and came to the house of a prostitute named Rahab, and lodged there.

In the same way, was Rahab the prostitute not justified by works too, when she received the [Hebrew] spies as guests and protected them, and sent them away [to escape] by a different route?
