Musar do Powtórzonego Prawa 1:11

יוסף עליכם ככם אלף פעמים . "May the Lord increase you a thousand fold more" (1,11). I have discovered among the writing of the Arizal that he sees the numerical value of משה as equal to א-ל שדי (345) and that when that name is spelled fully (in words instead of in letters), that the total amounts to 1000. Rashi comments that this thousand-fold blessing is Moses' own, whereas G–d Himself would add an additional dimension to it. Rashi, in saying זו משלי, meant that he blessed them with all that was contained in his name i.e. 1000. (יוד ,434=דלת ,360=שין ,74=למד ,111=אלף=20 plus 1 for the name itself =1000).
