'Wilderness' in the Bible

Now in those days comes John the baptist, preaching in the wilderness of Judaea,

For this is he who has been spoken of through Esaias the prophet, saying, Voice of him that crieth in the wilderness: prepare ye the way of the Lord, make straight his paths.

Then Jesus was carried up into the wilderness by the Spirit to be tempted of the devil:

But as they went away, Jesus began to say to the crowds concerning John, What went ye out into the wilderness to see? a reed moved about by the wind?

And his disciples say to him, Whence should we have so many loaves in the wilderness as to satisfy so great a crowd?
