Miriam and Aaron spoke against Moses because of the Cushite woman
whom he had married, for he had married a Cushite woman. And they
said, “Has the LORD indeed spoken only through Moses? Has he not
spoken through us also?” And the LORD heard it. Now the man Moses
was very meek, more than all people who were on the face of the
earth. And suddenly the LORD said to Moses and to Aaron and Miriam,
“Come out, you three, to the tent of meeting.” And the three of
them came out. And the LORD came down in a pillar of cloud and
stood at the entrance of the tent and called Aaron and Miriam, and
they both came forward. And he said, “Hear my words: If there is a
prophet among you, I the LORD make myself known to him in a vision;
I speak with him in a dream. Not so with my servant Moses. He is
faithful in all my house. With him I speak mouth to mouth, clearly,
and not in riddles, and he beholds the form of the LORD. Why then
were you not afraid to speak against my servant Moses?” And the
anger of the LORD was kindled against them, and he departed.

 When the cloud removed from over the tent, behold, Miriam was
leprous, like snow. And Aaron turned toward Miriam, and behold, she
was leprous. And Aaron said to Moses, “Oh, my lord, do not punish
us because we have done foolishly and have sinned. Let her not be
as one dead, whose flesh is half eaten away when he comes out of
his mother's womb.” And Moses cried to the LORD, “O God, please
heal her—please.” But the LORD said to Moses, “If her father had
but spit in her face, should she not be shamed seven days? Let her
be shut outside the camp seven days, and after that she may be
brought in again.” So Miriam was shut outside the camp seven days,
and the people did not set out on the march till Miriam was brought
in again. After that the people set out from Hazeroth, and camped
in the wilderness of Paran.
