'In the Wilderness' in the Bible

In those days came John the Baptist, preaching in the wilderness of Judaea,

For this is he that was spoken of through Isaiah the prophet, saying, "The voice of one crying in the wilderness, Prepare the way of the Lord, make straight his paths!"

If therefore they say to you, Lo! he is in the wilderness; go not forth; lo! he is in the private chambers; believe them not.
