5902. 'And He has established me as father to Pharaoh' means that now the natural was dependent on him. This is clear from the representation of 'Pharaoh' as the natural in general, dealt with in 5160, 5799. Dependence on him is meant by the words 'established as father', for sons are dependent on their father. In the proper sense 'father' means good, 2803, 3703, 3704, 5581; and since everything both in the internal man and in the external is dependent on good, God's establishing him as father to Pharaoh accordingly means that the natural was dependent on him, on good. For 'Joseph' represents the internal celestial, which is internal good, 5805, 5826, 5827, 5869, 5877. This good flows in and brings order to all things in the natural, and at length causes the natural to be dependent on it.

5805. 'And his brother is dead' means that internal good does not exist. This is clear from the representation of 'Joseph' as the celestial of the spiritual, dealt with in 4592, 4963, 5249, 5307, 5331, 5332, thus internal good since this is the same as the celestial of the spiritual; and from the meaning of 'being dead' as existing no more, dealt with in 494. There is this difference between the representation of 'Joseph' as internal good and the representation of 'Israel' as spiritual good: 'Joseph' is internal good springing from the rational, whereas 'Israel' is internal good springing from the natural, see 4286. This difference is like that between celestial good, or the good which is that of the celestial Church, and spiritual good, or the good which is that of the spiritual Church. These two kinds of good have been dealt with quite often in what has gone before. It is the first kind of internal good - celestial good - that is said to be non-existent there, which is meant by 'his brother is dead'.
