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.
Arcana Coelestia # 10234
10234. 'And Jehovah spoke to Moses, saying' means perception as a result of enlightenment from the Lord through the Word. This is clear from the meaning of 'Jehovah speaking to Moses' as enlightenment from the Lord through the Word, dealt with in 10215; and from the meaning of 'saying' as perception, dealt with in 2862, 3509, 5743, 8660. It should be remembered that when some new matter, distinct from what has gone before, is to be presented the words Jehovah spoke to Moses are used, as at verses 11, 17, 22, 34 of the present chapter, and also elsewhere. The new matter that is being presented now has regard to purification from evils and falsities.
