Dear Dr. Burton, Numbers 12:1 says that Miriam and Aaron spake against Moses because of the "Ethiopian" woman he had married. There is general disagreement as to whether that Ethiopian woman was Zipporah his wife (who was from Midian, where her father was from), or whether Moses had also married another woman in addition to Zipporah. Can you discuss the possibilities here, and where the preponderance of the evidence lies?
