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.

2849. 'Like the stars of the heavens' means a whole multitude of cognitions of good and truth. This is clear from the meaning of 'the stars' as cognitions of good and truth, dealt with in 1808, 2495. Those who are spiritual are compared in various places in the Word to 'the stars', this comparison being made for the reason that they possess cognitions of good and truth, whereas those who are celestial are not so compared because they do not possess cognitions but perceptions. And a further reason for the comparison is that the stars illuminate the night, and those who are spiritual have a night-time light - like that shed by the moon and stars - in comparison with the day-time light in which those dwell who are celestial. For more regarding the truth that those who are spiritual, compared with those who are celestial, dwell in obscurity, see 1043, 2708, 2715.
