Numbers 12:2-10

2And they said, Hath the LORD indeed spoken only by Moses? hath he not spoken also by us? And the LORD heard it . 3(Now the man Moses was very meek, above all the men who were upon the face of the earth.)

4And the LORD spoke suddenly to Moses, and to Aaron, and to Miriam, Come out ye three to the tabernacle of the congregation. And they three came out. 5And the LORD came down in the pillar of the cloud, and stood in the door of the tabernacle, and called Aaron and Miriam: and they both came forth. 6And he said, Hear now my words: If there is a prophet among you, I the LORD will make myself known to him in a vision, and will speak to him in a dream. 7My servant Moses is not so, who is faithful in all my house. 8With him will I speak mouth to mouth, even plainly, and not in dark speeches; and the similitude of the LORD shall he behold: why then were ye not afraid to speak against my servant Moses? 9And the anger of the LORD was kindled against them; and he departed.

10And the cloud departed from off the tabernacle; and, behold, Miriam became leprous, white as snow: and Aaron looked upon Miriam, and, behold, she was leprous.
