'Pharaoh,' in Genesis 40, represents the new natural self. 'Pharaoh' and 'the Egyptians' in the Word, signify the sensory and scientific principles. 'Let Pharaoh live,' as in Genesis 42:16, is a phrase that is employed to say something emphatically, thus to state a certainty. 'Pharaoh and his army' signify people who are in falsities from evil. 'Pharaoh' signifies false ideas infesting the truth of the church. It also signifies scientific ideas, or the natural principle in general.
