Image (dimyon) is that which has been stated:... and by the hand of the prophets I shall be imagined (adameh). (Hos. 12:11) And upon that it is stated: (Num. 12:8)... and the depiction of Y”Y he will behold.
Because all the countenances of the prophets, are inscribed in it (Malkhut), it is called dimyon (imagination).
And because all the lights which are above it (Malkhut) are seen through it, it is called mar-eh (appearance). It is this that is written: (Num. 12:6)... Y”Y, in appearance (mar-eh), I shall become known to him.
