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.

8063. 'Within all your borders' means within the range of truth that springs from good. This is clear from the meaning of 'borders' as the range of truth springing from good. For every truth has its own range, which is sometimes manifested in a sphere; and because it has its own range it has its own 'borders'. The sphere belonging to the range of truth is subject to the nature and amount of good, for good is like a flame and truth like the light from it. In the spiritual world a sphere extends to communities round about, and its range determines the range of communication there, see 6598-6613. Everyone in heaven has intelligence and wisdom, also happiness, in proportion to that extending sphere, that is, in proportion to the strength and at the same time the character of it. From this one may see what 'in all the borders' means in the spiritual sense, here that good must have nothing false within it. For false ideas lie outside the sphere; they begin where the truths leave off. But if they enter the sphere they are assimilated. The idea that they must not enter is meant by the words 'nothing made with yeast shall be seen among you' nor 'yeast within all your borders'.
