Tzipporah was a dark-skinned Midianite (Ibn Ezra; Radak, Sherashim). Kushite in Hebrew, literally Ethiopian (cf. Targum Yonathan; Rashbam; Septuagint). It is from here that the tradition is derived that after he escaped from Egypt, Moses was a ruler in Ethiopia, and married an Ethiopian princess (Rashbam; Sefer HaYashar; Divrey Yamim DeMoshe; Yalkut Shimoni 168; Rashbam; Josephus, Antiquities 2:10:2). Or, 'a beautiful wife' (Targum; Saadia; Rashi; HaKethav VeHaKabbalah); or, 'a distinguished wife' (Rashi).
Or, 'for he had divorced his beautiful wife' (Targum; Saadia; Rashi).
