Kedar
   dark-skinned, the second son of Ishmael (Gen. 25:13).
   
     It is the name for the nomadic tribes of Arabs, the Bedouins
   generally (Isa. 21:16; 42:11; 60:7; Jer. 2:10; Ezek. 27:21), who
   dwelt in the north-west of Arabia. They lived in black
   hair-tents (Cant. 1:5). To "dwell in the tents of Kedar" was to
   be cut off from the worship of the true God (Ps. 120:5). The
   Kedarites suffered at the hands of Nebuchadnezzar (Jer. 49:28,
   29).
