6528. 'And his father's house' means spiritual good. This is clear from the representation of Israel, to whom 'father' refers here, as spiritual good, dealt with in 3654, 4598, 5801, 5803, 5806, 5812, 5817, 5819, 5826, 5833. Consequently 'his house' means all the characteristic features in their entirety of that good.

5812. 'The boy cannot leave his father' means that that truth cannot be separated from spiritual good. This is clear from the meaning of 'leaving' as being separated; from the representation of 'Israel' as spiritual good from the natural, dealt with in 4286, 4598, 5807; and from the representation of 'Benjamin' as new truth, dealt with in 5804, 5806. This truth is called 'the boy' because it is born last; for this truth is not born until a person has become regenerate. At this point he receives newness of life through this new truth joined to good, which also is why this truth is meant by 'a child of his old age, the youngest one', 5804.
