“Uzal” means separate

Uzal: the sixth son of Joktan, (Genesis 10:27; 1 Chronicles 1:21) whose settlements are clearly traced in the ancient name of San'a , the capital city of the Yemen (a district of Arabia), which was originally Awzal . From its position in the centre of the best portion of that kingdom it must always have been an important city. (San'a is situated about 150 miles from Aden and 100 miles from the coast of the Red Sea. It is one of the most imposing cities of Arabia -ED.)
