זוהר שמות — דף רנז ע”א

Abraham, representing the right side and divine love, takes hold of the palace called El Shadai. The celestial breasts fill with all goodness to nourish and sustain the entire world. At creation, the world could not stand until Abraham revealed this palace by saying enough. Isaac represents the left side, source of all judgments, linked to the palace called Zekhut (merit). The two palaces unite, for the right encompasses the left, as Abraham bound Isaac at the Akeidah.
