Numbers 12:4-10

4And the Lord suddenly said to Moses and to Aaron and Miriam, “You three go out to the tent of meeting.” So the three of them went out. 51Then the Lord came down in a pillar of cloud and stood at the entrance of the tent; and He called Aaron and Miriam. When they had both come forward, 6He said, “Now hear My words: If there is a prophet among you, I, the Lord, will make Myself known to him in a 2vision. I will speak with him in a 3dream.7It is not this way for 4My servant Moses; 5He is faithful in all My household;86With him I speak mouth to mouth, That is, openly, and not 7using 8mysterious language, And he beholds 9the form of the Lord. So why were you not afraid To speak against My servant, against Moses?”

9And the anger of the Lord burned against them and 10He departed. 10But when the cloud had withdrawn from above the tent, behold, 11Miriam was leprous, as 12white as snow. As Aaron turned toward Miriam, behold, she was leprous.
