Kabbalah su Numeri 12:10

Four husks, four worlds to twenty-one of them, in them ten sefirot in five faces, that the fixings (tikunim) of the lower ones are in four worlds, and their defects in four worlds. If the lower ones merit, the Lord leads with mercy, and the guard goes from in front of him (away). If they sinned, the Master of Mercy separates himself, and the guard does justice on the guilty ones. With the separation of the Lord, the deed of the guard, is what is written: "And the anger of Hashem flared against them, and He went away, and the cloud departed from over the tent, and behold Miriam was leprous as snow" (Numbers 12:10).
