Numbers 12:7

The LORD spoke suddenly to Moses, to Aaron, and to Miriam, “You three come out to the Tent of Meeting!”

The three of them came out.

The LORD came down in a pillar of cloud, and stood at the door of the Tent, and called Aaron and Miriam; and they both came forward.

He said, “Now hear my words. If there is a prophet among you, I, the LORD, will make myself known to him in a vision. I will speak with him in a dream.

With him, I will speak mouth to mouth, even plainly, and not in riddles; and he shall see the LORD’s form. Why then were you not afraid to speak against my servant, against Moses?”

The LORD’s anger burned against them; and he departed.

The cloud departed from over the Tent; and behold, Miriam was leprous, as white as snow. Aaron looked at Miriam, and behold, she was leprous.
