'Spy' in the Bible

But Rahab the harlot, and her father's household, and all that she had, did Joshua save alive; and she dwelt in the midst of Israel unto this day, because she hid the messengers, whom Joshua sent to spy out Jericho.

And Joshua sent men from Jericho to Ai, which is beside Beth-aven, on the east side of Beth-el, and spake unto them, saying, Go up and spy out the land. And the men went up and spied out Ai.

Forty years old was I when Moses the servant of Jehovah sent me from Kadesh-barnea to spy out the land; and I brought him word again as it was in my heart.
