Arcana Coelestia #8085
8085. 'And so it was when Pharaoh hardened himself against sending us away' means when those who molested by means of falsities were obstinately determined not to let them be released. This is clear from the meaning of 'hardening oneself' as being obstinately determined, dealt with in 7272, 7300, 7305; from the representation of 'Pharaoh' as those who molested by means of falsities, dealt with in 7107, 7110, 7126, 7142, 7220, 7228, 7317; and from the meaning of 'sending away' as releasing.
Arcana Coelestia #7228
7228. 'And for Pharaoh king of Egypt' means the warning to be given to those who molest by means of utter falsities. This is clear from the meaning of 'speaking to', when it comes by Divine command and is directed to those steeped in falsities, as a warning, as above in 7220; and from the representation of 'Pharaoh', when he is also called 'king of Egypt', as those who molest by means of utter falsities, dealt with above in 7220.
