'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.

Firstborn, in a supreme sense, represents the Lord as to divine celestial love, and also peope who were of the celestial church. The sanctification of the firstborn, as in Exodus 13, signifies faith in the Lord. The firstborn, in the spiritual sense of the Word, is good, for with infants the good of innocence is first infused by the Lord, by virtue of which man first becomes a man. Since good is of love, and man does not reflect upon his own love, but only upon the thoughts of his memory, and since good has not at first a quality, but acquires one when it is formed in truths, and without a quality nothing is perceived, hence it was unknown that good was the primary principle, or firstborn. Good is first conceived from the Lord in man, and is produced by truths, in which good is manifested, in its own form and effigy. Firstborn, as in Psalm 89:28, signifies the Lord's humanity.
