Cushite
(1.) The messenger sent by Joab to David to announce his victory
over Absalom (2 Sam. 18:32).

  (2.) The father of Shelemiah (Jer. 36:14).

  (3.) Son of Gedaliah, and father of the prophet Zephaniah
(1:1).

  (4.) Moses married a Cushite woman (Num. 12:1). From this
circumstance some have supposed that Zipporah was meant, and
hence that Midian was Cush.
