7336. 'And there was blood in the entire land of Egypt' means total falsification, see above in 7327.

7327. 'And there will be blood in all the land of Egypt' means total falsification. This is clear from the meaning of 'blood' as the falsification of truth, dealt with immediately above in 7326; and from the meaning of 'in all the land of Egypt' as everywhere, thus total falsification. Total falsification takes place when falsity begins to reign, for a person then leads a life in keeping with his congenital and acquired evil, and finds delight in it. And since the truths of faith forbid such things he loathes them; and when he loathes truths wherever they exist, he casts them away from himself, or if he cannot do this he falsifies them.
