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.

340. That 'she said, I have gained a man, Jehovah' means that with those called Cain faith was known and acknowledged as something existing by itself is clear from what has been stated in the preliminary sections of this chapter. ¹ Previously they had not so to speak known what faith was, for what they possessed was a perception of everything that constituted faith. But once they started to make distinct and separate doctrine out of faith they drew on things which had been with them matters of perception and reduced them to doctrine. This doctrine they called 'I have gained a man, Jehovah', as though they had come upon something new. So that which had previously been written on the heart was now made into factual knowledge. In early times people used to find a name for anything that was new, and used to attach explanations as to what such names embodied. For example, to indicate what Ishmael meant, the explanation was added, Jehovah hearkened to her affliction', Genesis 16:11; what Reuben meant, 'Jehovah has seen my affliction', Genesis 29:32; what Simeon meant, 'Jehovah heard that she was less loved', ibid. Verse 33; and what Judah meant, 'This time I will confess Jehovah', ibid. Verse 35. The altar built by Moses was called 'Jehovah is my banner', Exodus 17:15. And here likewise doctrine concerning faith is called 'I have gained a man, Jehovah', which is what Cain meant.
