what does the bible say?
The Bible doesn't provide a clear answer to whether Moses had more than one wife. The question arises from Aaron and Miriam's confrontation of Moses about his "Cushite wife" (Numbers 12:1). Since Scripture indicates that Moses had married a Midianite woman named Zipporah (Exodus 2:16-21), Aaron and Miriam's accusation raises the question of whether Moses married a second time. Though Zipporah may have died, leaving Moses free to marry, the Bible doesn't indicate this. Another theory is that he could have taken a second wife. This would mean that Moses, a faithful servant of God (Numbers 12:7; Hebrews 3:5) who handed down God's commandments to the Israelites, would have violated the Deuteronomy 17:17 law about not acquiring "many wives," but that also does not seem likely. Yet another theory is that Zipporah was the Cushite woman. Buttressing this view is a passage in Habakkuk that suggests that Cushites and Midianites may have been the same people (3:7). Ultimately, whether Moses had one wife or two is not as important as his singleminded devotion to the one true God (Numbers 12:7; Hebrews 3:5).
