'Spy' in the Bible

However, Rahab the harlot and her father’s household and all she had, Joshua spared; and she has lived in the midst of Israel to this day, for she hid the messengers whom Joshua sent to spy out Jericho.

Now Joshua sent men from Jericho to Ai, which is near Beth-aven, east of Bethel, and said to them, “Go up and spy out the land.” So the men went up and spied out Ai.

I was forty years old when Moses the servant of the Lord sent me from Kadesh-barnea to spy out the land, and I brought word back to him as it was in my heart.
