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.

5913. 'And your flocks, and your herds' means natural good, interior and exterior. This is clear from the meaning of 'flock' as interior good, dealt with in 2566, in this case interior natural good since the flocks belonged to Israel, who represents spiritual good from the natural, 5906; and from the meaning of 'herd' as exterior natural good. The reason why 'herd' means exterior good and 'flocks' interior good is that the animals which constituted a herd, such as oxen and young bulls, were signs, when used in sacrifices, of external forms of the good of charity and also of the forms of good present in the external man. But the animals constituting flocks, such as lambs, sheep, she-goats, were signs of internal forms of the good of charity and also of the forms of good present in the internal man. Consequently people in whom these forms of good are present are referred to in the Word by the single term 'flock', and the one who leads them by the term 'pastor' or 'shepherd'.
