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.

9417. 'And the law and the commandment' means truth in general and in particular. This is clear from the meaning of 'the law' as truth in general; and from the meaning of 'the commandment' as truth in particular. In the Word laws are divided up into commandments, judgements, and statutes, 'commandments' being used to mean laws of life, 'judgements' to mean laws of the civic state, and 'statutes' to mean laws of worship, 8972. However, all these together are called by the general term 'the law', and the individual requirements of the law are called 'commandments', as is clear from a large number of places in the Word. So it is that when the expression 'the law and the commandment' is used, truth in general and in particular is meant.
