THE LIKENESS OF THE KING.
Rabbi Pinchas, explaining the passage (Numb. xii.), "The likeness of God appeared unto him" [Moses], said, in the name of Rabbi Hosea: "This may be likened to an earthly king who shows himself in his true likeness only to a child of his own household. For in this world the divine glory is only revealed to individuals; but in the world to come God in His glory will be revealed to all. As it is written (Isa. xl.), 'And the glory of the Eternal shall be revealed, and all flesh together shall see, for the mouth of the Eternal hath spoken it.'"
Vayikra Rabbah, I.
