A few more words about this episode
An Ethiopian woman (v.1)
Aaron and Miriam criticize Moses for marrying an Ethiopian woman.
So who is Moses's Ethiopian wife? The only wife we know of so far is Zipporah, and she was from Midian not Ethiopia. So did Moses have two wives? And what were Aaron and Miriam complaining about? That he married a non-Hebrew woman? That he married a black woman? Or that he already had a wife (which he apparently abandoned) and was marrying another?
