Numbers 12:1-10 (NKJV)
[1] Then Miriam and Aaron spoke against Moses because of the Ethiopian woman whom he had married; for he had married an Ethiopian woman.
[2] So they said, “Has the Lord indeed spoken only through Moses? Has He not spoken through us also?” And the Lord heard it.
[3] (Now the man Moses was very humble, more than all men who were on the face of the earth.)
[4] Suddenly the Lord said to Moses, Aaron, and Miriam, “Come out, you three, to the tabernacle of meeting!” So the three came out.
[5] Then the Lord came down in the pillar of cloud and stood in the door of the tabernacle, and called Aaron and Miriam. And they both went forward.
[6] Then He said,
“Hear now My words:
If there is a prophet among you,
I, the Lord, make Myself known to him in a vision;
I speak to him in a dream.
[7] Not so with My servant Moses;
He is faithful in all My house.
[8] I speak with him face to face,
Even plainly, and not in dark sayings;
And he sees the form of the Lord.
Why then were you not afraid
To speak against My servant Moses?”
[9] So the anger of the Lord was aroused against them, and He departed.
[10] And when the cloud departed from above the tabernacle, suddenly Miriam became leprous, as white as snow. Then Aaron turned toward Miriam, and there she was, a leper.
