After the joining of spiritual good from the natural, which is 'Israel', to the internal celestial, which is 'Joseph', has been effected, which was the subject in the previous chapter, the present chapter deals in the internal sense with the introduction of the Church's truths within the natural into factual knowledge. The Church's truths in the natural are 'the sons of Jacob'; truth itself as a whole there is 'Jacob'; and the factual knowledge into which those truths are introduced is 'Pharaoh'.
