'In the Wilderness' in the Bible

AND in those days came John the Baptist preaching in the wilderness of Judea, saying,

For this is he that was spoken of by Isaiah the prophet, saying; A voice of one crying in the wilderness, Prepare the way of the Lord, make his paths straight.

But his disciples said to him, Whence shall we obtain so much bread in the wilderness as to fill so great a multitude?

If, therefore, they say to you, Behold he is in the wilderness, go not forth; Behold he is in private rooms, believe it not.
