Numbers 12:1, 4, 9-10

Miriam and Aaron spoke against Moses because of the Cushite woman whom he had married, for he had married a Cushite woman.

And suddenly the LORD said to Moses and to Aaron and Miriam, “Come out, you three, to the tent of meeting.” And the three of them came out.

And the anger of the LORD was kindled against them, and he departed. When the cloud removed from over the tent, behold, Miriam was leprous, like snow. And Aaron turned toward Miriam, and behold, she was leprous.
