Numbers 12:4-11

Suddenly the LORD said to Moses, Aaron, and Miriam, "Come out, you three, to the tabernacle of meeting!" So the three came out.

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.

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.

Not so with My servant Moses; He [is] faithful in all My house.

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?"

So the anger of the LORD was aroused against them, and He departed.

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.

So Aaron said to Moses, "Oh, my lord! Please do not lay [this] sin on us, in which we have done foolishly and in which we have sinned.
