'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 by the prophet Esaias, saying, The voice of one crying in the wilderness, Prepare ye 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 they departed, Jesus began to say unto the multitudes concerning John, What went ye out into the wilderness to see? A reed shaken with the wind?

And his disciples say unto him, Whence should we have so much bread in the wilderness, as to fill so great a multitude?
