'Desert' in the Bible

Now these [are] the sons of Zibeon: Aiah and Anah--he [is] Anah who found the hot springs in the desert while he pastured the donkeys of Zibeon his father.

And Reuben said to them, "You must not shed blood. Throw him into this pit that [is] in the desert, but do not lay a hand on him"--so that he might rescue him from their hand to return him to his father.
