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.

4513. Verses 30-31 And Jacob said to Simeon and to Levi, You have brought trouble on me, by making me stink to the inhabitant of the land, to the Canaanite and the Perizzite; and I am [a few] mortals in number, and they will be gathered together against me and will smite me, and I shall be destroyed, I and my house. And they said, Is he going to treat our sister like a prostitute?

'Jacob said' means the external Ancient Church. 'To Simeon and Levi' means that which was the representative of spiritual and celestial things. 'You have brought trouble on me, by making me stink to the inhabitant of the land' means that those who belonged to the Ancient Church abominated them. 'To the Canaanite and the Perizzite' means those who are governed by good and truth. 'And I am [a few] mortals in number' means that it would be easy.... 'And they will be gathered together against me and will smite me, and I shall be destroyed' means, for the Ancient Church so to perish. 'I and my house' means as regards truth and good. 'And they said' means the reply. 'Is he going to treat our sister like a prostitute?' means on account of the fact that they had no affection [for truth].
