“Moses, like Joseph would be in Egypt. Joseph and Moses were mistaken for Egyptians not because they dressed like them; but because they looked like them (Gen. 42: 8, Ex. 2: 19)!
Moses does the unthinkable in Numbers 12: 1 which says, “And Miriam and Aaron spake against Moses because of the Ethiopian woman whom he had married: for he had married an Ethiopian woman.” Why were they upset? It couldn’t have been because of the color of their skin, because God says they came out from Ethiopia: Amos 9: 7 says, “Are ye not as children of the Ethiopians unto me, O children of Israel? Saith the LORD. Have not I brought up Israel out of the land of Egypt? And the Philistines from Caphtor, and the Syrians from Kir?” Being in a place 400 years wouldn’t change the color of your skin; but intermarriage will.
Moses didn’t just marry this woman, but she had always been his wife. She was a reminder of where they just came out of. This woman was Zipporah daughter of Jethro in the land of Midian: Exodus 2: 21-22 says, “And Moses was content to dwell with the man: and he gave Moses Zipporah his daughter. And she bare him a son, and he called his name Gershom: for he said, I have been a stranger in a land.” But the backstory of Numbers 12 is when Moses and the children of Israel had come out of Egypt he gave his wife Zipporah back to his father in law: Exodus 18: 1-2 says, “When Jethro, the priest of Midian, Moses’ father in law, heard of all that God had done for Moses, and for Israel his people, and that the LORD had brought Israel out of Egypt; Then Jethro, Moses’ father in law, took Zipporah, Moses’ wife after he had sent her back,” The phrase “… he had sent her back” means he divorced her and sent her back to Jethro with the children he had with her: Exodus 18: 2d-6 says’ “… after he had sent her back, And her two sons; of which the name of the one was Gershom; for he said, I have been an alien in a strange land: And the name of the other was Eliezer; for the God of my father, said he was mine help, and delivered me from the sword of Pharaoh: And Jethro, Moses’ father in law, came with his sons and his wife unto Moses into the wilderness, where he encamped at the mount of God: And he said unto Moses, I thy father in law Jethro am come unto thee, and thy wife, and her two sons with her.” Therefore, Aaron and Miriam were angry” – Anthony D.
