'Spy Out the Land' in the Bible

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.
