'Wilderness' in the Bible

And in those days cometh John the Baptist, preaching in the wilderness of Judaea, saying,

For this is he that was spoken of through Isaiah the prophet, saying, The voice of one crying in the wilderness, Make ye ready the way of the Lord, Make his paths straight.

Then was Jesus led up of the Spirit into the wilderness to be tempted of the devil.

And as these went their way, Jesus began to say unto the multitudes concerning John, What went ye out into the wilderness to behold? a reed shaken with the wind?

If therefore they shall say unto you, Behold, he is in the wilderness; go not forth: Behold, he is in the inner chambers; believe it not.
