Numbers 12:7

4 And suddenly the Lord said to Moses and Aaron and Miriam, Come out, you three, to the Tent of meeting. And the three of them went out.

5 And the Lord came down in a pillar of cloud, taking his place at the door of the Tent, and made Aaron and Miriam come before him.

6 And he said, Now give ear to my words: if there is a prophet among you I will give him knowledge of myself in a vision and will let my words come to him in a dream.

7 My servant Moses is not so; he is true to me in all my house:

8 With him I will have talk mouth to mouth, openly and not in dark sayings; and with his eyes he will see the form of the Lord: why then had you no fear of saying evil against my servant Moses?

9 And burning with wrath against them, the Lord went away.

10 And the cloud was moved from over the Tent; and straight away Miriam became a leper, as white as snow: and Aaron, looking at Miriam, saw that she was a leper.
