זוהר דברים — דף רפג ע”ב

The Zohar comments on the verse 'Moses went and spoke these words to all Israel'. Rabbi Hizkiya opens with the verse 'He led at the right hand of Moses His glorious arm'. The Zohar emphasizes that Moses was connected to the right arm of the Holy Blessed One, which is the attribute of lovingkindness (Chesed), and elaborates on the unique and special bond between Moses and the Holy Blessed One.
