Arab in the Bible

Arab and Dumah and Eshan,

But when Sanballat the Horonite and Tobiah the Ammonite official, and Geshem the Arab heard it, they mocked us and despised us and said, “What is this thing you are doing? Are you rebelling against the king?”

Now when it was reported to Sanballat, Tobiah, to Geshem the Arab and to the rest of our enemies that I had rebuilt the wall, and that no breach remained in it, although at that time I had not set up the doors in the gates,

It shall not be dwelt in for ever, Neither shall it be inhabited from generation to generation, - Neither shall encamp there, an Arab, Nor, shepherds, fold their flocks there.

Therefore the wealth they have acquired and what they have stored up they carry them away over the Arab Wadi.

“Lift up your eyes to the bare heights and see;
Where have you not been violated?
By the roads you have sat for them
Like an Arab in the desert,
And you have polluted a land
With your harlotry and with your wickedness.
