Albert Barnes Commentary Jeremiah 25:24

"and all the kings of Arabia, and all the kings of the mingled people that dwell in the wilderness;" — Jeremiah 25:24 (ASV)

Arabia - That part which bordered on Palestine, and was inhabited mainly by Ishmaelites.

The mingled people - Compare the Jeremiah 25:20 note. In Arabia there seem to have been many tribes of Cushite origin, who by intermarriage with other tribes had become of mixed blood.
