Arcana Coelestia # 3029
3029. 'The servant said to him' means the Lord's perception concerning the natural man. This is clear from the meaning of 'saying' as perceiving, dealt with in 1791, 1815, 1819, 1822, 1898, 1919, 2080, 2506, 2515, 2552, and from the meaning of 'the servant' here as the natural man, dealt with above in 3019, 3020. All that takes place in the natural man, and what the natural man is like, is perceived in the rational, for that in man which is lower is perceived from that which is higher, see 2654. Consequently 'the servant said to him' means the Lord's perception concerning the natural man.
House
A "house" is essentially a container -- for a person, a family, several families or even a large group with shared interests (think of the term "houses of worship.") In the Bible, a "house" is also a container, but for spiritual things rather than natural things. In various uses a "house" can represent part of the mind, the whole mind, a whole person or even a church. The other nuance to the word "house" is that it is generally used in regards to our affections and desires rather than our thoughts and principles. This makes sense; we tend to engage our thoughts and rationality when we are out in the world doing our work, but when we are inside our houses we are driven most by love for our families and the desire to be good to those we love. So "house" tends to represent the things we want and care about -- which are ultimately the things that define us.
