Musar su Giosuè 22:22

The subject of דבקות to the Ineffable Name can be approached from two directions. One approach is by pointing out how G–d employed His Ineffable Name to be active in the emanations which initiated the בנין, i.e. the work of the six days of creation commencing from the emanation תפארת "downwards," up to and including מלכות, the seventh emanation, the Sabbath. Israel's connection with the emanation תפארת through the choicest of the patriarchs -Jacob- in his capacity as ישראל, i.e. the major part of the מרכבה, (although the other patriarchs also serve as part of the מרכבה) because מטתו שלמה, his demonstrated ability to raise all his children loyal to G–d's precepts, has already been discussed elsewhere.
