337. This verse is such, "Your father's wife" we have learned. As long as the Queen is with the King and she nurtures you, FROM HER ABUNDANCE, she is called your mother. Now, IN EXILE, she has been exiled with you and is far from the King, so she is called "your father's wife." She is the wife of the Holy King, ZEIR ANPIN, as she was never set free with a divorce. She is surely His wife, as it is written, "Thus says Hashem, Where is the bill of your mother's divorcement, with which I have put her away?" (Yeshayah 50:1). Surely she is the wife of the King even though she was exiled.
