6583. 'And Joseph saw Ephraim's sons of the third generation' means the establishment of the Church so far as its understanding and the derivatives from this were concerned. This is clear from the representation of 'Ephraim' as the area of understanding in the Church, dealt with in 3969, 5354, 6222, 6274, 6238, 6267; and from the meaning of 'sons of the third generation' as derivatives, for being the descendants of their parent, 'sons and 'sons of sons' mean the thing represented by that parent. The establishment of the Church from the internal, that is, from the Lord through the internal, is meant by 'Joseph saw'. What the Church's understanding is which 'Ephraim' represents, see 6222.
