Beshalach: Chapter 28
"And He said, 'If you will diligently hearken to voice of Hashem'"

When they attained the Covenant, the children of Yisrael attained Malchut, Yesod, Netzach and Hod, and therefore reached the Holy King, Tiferet. We learn of the proper circumcision and uncovering and the holy anointing oil that allow the circumcised to bond with the Holy King. The text speaks of the protection for the holy mark for four things. The children of Yisrael merit welcoming the Shechinah through guarding against the impurity of menstruation. We hear of the protection of the Righteous, protection from the maidservant, protection from a heathen woman and protection from a harlot. We read that God did not want to give the children of Yisrael the Torah until they were close to Him, and He achieved this closeness by the Covenant of circumcision.
