And about Him it is stated: (Esth. 2:7) And he was the guardian (omen) of Hadassah... He is Her oman (guardian), and She is His emunah∞ward (faith). And this is that which is stated: (Esth. 2:20)... as she was in trust (omnah) with him. And no alien had touched her – by which is meant Aḥ-ashverosh, because Her ‘brother’ is with Her surely. And He hides (satir) Her from him.
With what does He hide Her from him? With the point which is the tip of the letter Dalet ד of the word EḤaD (One). AḤ∞brother protects Dalet ד, so that ‘another’∞AḤeR does not approach Her. It is this that is written: (Is. 42:8) I am Y”Y, That is My Name, and My Glory I shall not give to another... And this point is the sign of the covenant, in which aḥ∞brother (=9) is completed to ten, and with Her is made Yod י (=10).
