Numbers 12:5-10

ADONAI came down in a column of cloud and stood at the entrance to the tent. He summoned Aharon and Miryam, and they both went forward.

He said, "Listen to what I say: when there is a prophet among you, I, ADONAI, make myself known to him in a vision, I speak with him in a dream.

But it isn't that way with my servant Moshe. He is the only one who is faithful in my entire household.

With him I speak face to face and clearly, not in riddles; he sees the image of ADONAI. So why weren't you afraid to criticize my servant Moshe?"

The anger of ADONAI flared up against them, and he left.

But when the cloud was removed from above the tent, Miryam had tzara'at, as white as snow. Aharon looked at Miryam, and she was as white as snow.
