Arabia is not often referred to by this name in the Bible, since its inhabitants were generally known by the political or tribal names of the smaller groups to which they belonged.
In the time of Hezekiah these people were very familiar (Isaiah 13:20; 21:13), and some even served as mercenaries in the defense of Jerusalem against Sennacherib. In the time of Josiah (Jeremiah 3:2) and in the closing days of the kingdom of Judah, the Arabians were coming to prominence as traders (Jeremiah 25:23-24; Ezekiel 27).
Arabia did not, as it does today, denote the whole of the great peninsula between the Red Sea and the Persian Gulf, but only the area to the immediate east and south of Palestine. [Tyndale House, The Illustrated Bible Dictionary, Vol. 1, pp. 83-86]
