זוהר שמות — דף רכז ע”א

The secret of the Torah emerges from that great voice, which is the supreme King. Mount Sinai is the 'couch' of the King, and 'my nard gave its fragrance' represents the Knesset Israel which said 'we will do and we will hear'. Thus the Tabernacle received the secret of Sinai and was established within it. The entire accounting of the Tabernacle was bound to the secret of the letters, and all is included in the one.
