Numbers 12:1, 4, 9-10

And Miriam and Aaron spake against Moses because of the Cushite woman whom he had married; for he had married a Cushite woman.

And Jehovah spake suddenly unto Moses, and unto Aaron, and unto Miriam, Come out ye three unto the tent of meeting. And they three came out.

And the anger of Jehovah was kindled against them; and he departed. And the cloud removed from over the Tent; and, behold, Miriam was leprous, as white as snow: and Aaron looked upon Miriam, and, behold, she was leprous.
