זוהר שמות — דף ריז ע”א

In the redemption, one must mention emet four times until Ezrat Avoteinu, then four more times, to seal the four redemptions with the royal signet. The Exodus from Egypt must be recalled in all sanctifications, for through kedusha all are sanctified above and below. The words of the righteous ascend and are spoken before the King, who delights in them and crowns Himself with them. Blessed is one who awakens these holy words in this world.
