Kedar 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 northwest of Arabia. They lived in black hair-tents (Song of Songs 1:5). To “dwell in the tents of Kedar” was to be cut off from the worship of the true God (Ps. 120:5). http://www.christiananswers.net/dictionary/kedar.html
