Numbers 12:8-10

Young's Literal Translation

⁸ mouth unto mouth I speak with him, and [by] an appearance, and not in riddles; and the form of Jehovah he beholdeth attentively; and wherefore have ye not been afraid to speak against My servant -- against Moses?'

⁹ And the anger of Jehovah burneth against them, and He goeth on,

¹⁰ and the cloud hath turned aside from off the tent, and lo, Miriam [is] leprous as snow; and Aaron turneth unto Miriam, and lo, leprous!
