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 # 10039
10039. 'It is a sin [offering]' means that which has been purified in this manner from evils and falsities. This is clear from the meaning of 'sin', when this word is used to mean a sacrifice, as purification from evils and falsities. For in the original language, when sacrifices are the subject, sin is used to mean a sacrifice for sin; and by sacrifice purification from evils and falsities is meant, 9990, 9991. The fact that in the Word a sacrifice for sin is called a sin [offering], see Leviticus 4:3, 8, 14, 20-21, 24-25, 29, 33-34; 5:6, 8-9; 6:17, 25-26, 30, and elsewhere.
