'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 by the prophet Esaias, saying, The voice of one crying in the wilderness, Prepare ye the way of the Lord, make his paths straight.

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