8151. And Jehovah hardened the heart of Pharaoh. That this signifies obstinacy from the falsity which is from evil, is evident from the signification of “hardening the heart,” as being to be determined (see n. 7272, 7300, 7305, 7616). Its being said that “Jehovah hardened Pharaoh’s heart” signifies, in the internal sense, that they who are in evil and falsity hardened themselves, thus that the evils and falsities themselves did this (see n. 2447, 6071, 6991, 6997, 7533, 7643, 7877, 7926).

7616. And the heart of Pharaoh was made firm. That this signifies that from evil they were determined, is evident from the signification of the “heart being made firm,” as being to be determined (as just above, n. 7615), where it is said that “he made his heart heavy;” the difference being that “to make the heart heavy” is from falsity, but “to make the heart firm” is from evil.
