זוהר שמות — דף רכב ע”א

The flour jar, measured precisely, never ceased to be blessed by the merit of Elijah. Likewise, the tabernacle accounted measure by measure never ceased to be blessed because it was overseen by Moses. Moses separated from his wife to cleave to the Shekhinah and was appointed as great steward of the house. Betsalel came from the right side and Oholiab from the left, and Moses between them erected the whole. It is by virtue of Moses's word that the entire construction was sustained in divine blessing.
