'Desert' in the Bible

He said, “I am the voice of one shouting in the wilderness, ‘Make straight the way of the Lord,’ as the prophet Isaiah said.”

Just as Moses lifted up the [bronze] serpent in the desert [on a pole], so must the Son of Man be lifted up [on the cross],

For that reason Jesus no longer walked openly among the Jews, but left there and went to the district that borders on the uninhabited wilderness, to a town called Ephraim; and He stayed there with the disciples.
