Buz in Fausset's Bible Dictionary

("contempt".) 1. Second son of Milcah and Nahor, Abraham's brother (Genesis 22:21). Kennel was the father of Aram, i.e. Syria. Elihu (Job 32:2) is called "the son of Barachal the Buzite, of the kindred of Ram" (i.e. Aram); he therefore probably was descended from Buz. The family settled in Arabia Deserta, for Jeremiah (Jeremiah 25:23), in denouncing judgments against Buz, associates the tribe with Tema and Dedan. 2. The name also occurs in Gad's genealogy (1 Chronicles 5:14).
