In chapter 12, the story becomes one of opposition, hard hearts, and divisions within the camp. The opposition that Moses is now facing comes from within his own family circle, from his brother Aaron and his sister, Miriam, who seems to be the ringleader. The ground for this attack was the fact that Moses had taken a Cushite wife. Moses’ first wife, Zipporah, was from Midian, and so it seems that she had died and that Moses had taken a second wife who was Ethiopian. If this is correct, then Miriam was saying, “I don’t like this black woman in my family.” So it’s not only sibling rivalry, it’s the worst kind of racial prejudice.
