זוהר שמות — דף קיו ע”ב

Yeqev means: Unity, Holiness, Blessing of the Holy One blessed be He, and this is the Shekhinah. One who masters the halakhah — the Shekhinah — the Holy One blessed be He is with him forever. The Halakhah given to Moses from Sinai: the Holy One gave him His daughter. The Faithful Shepherd opens on: "The angel who redeems me from all evil" — this is the Shekhinah. The kelipot — skin, flesh, bones and sinews — stifle the spirit which cannot see upward. One who masters halakhah, the Holy One will never depart from him. In the future the Shekhinah will no longer be covered by sins, as it is said: "Your Teacher will no longer hide Himself."
