And it the right-hand of YQV”Q is in exile with the Shekhinah, and It supports Her. And the mystery of the word is: (Is. 53:1) And the arm of Y”Y – upon whom (miy) has it been revealed?
And through It is the promise of redemption. It is this that is written: (Is. 62:8) Y”Y has sworn by His right-hand, and by His arm of strength... And furthermore: (Ruth 3:13)... as Y”Y lives, lie down until the morning.
And why is it called the ‘arm of Y”Y’? Because the palm of the hand has within it a י Yod [Var. YOD יוד ], the five fingers are Hei ה (=5), the windpipe of the right, which is the arm, Vav ו, the shoulder has within it Hei ה. And this is ‘the Middle Pillar’ (Tipheret), which is bound with the right, to raise up the Shekhinah in exile.
