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.

2559. 'It happened, when God caused me to depart from my father's house' means when He left behind factual knowledge and the appearances that arise from this, together with their delights, meant here by 'father's house'. This is clear from the meaning of 'departing' as leaving behind, and from the meaning of 'house' as good, 2233, here the good that consists in the delight received from the appearances that go with factual knowledge and rational concepts, for all delight appears as good. The reason 'father's house' here means the delights received from factual knowledge and rational concepts, and therefore from the appearances that go with these, is that they are spoken of in reference to Abraham when he departed from his father's house, for at that time, together with his father's house, Abraham worshipped other gods; see 1356, 1992. This explains why the verb in the clause God caused me to depart is plural. This clause, as is also in keeping with the original language, could be rendered, the gods caused me to wander, but because the Lord is represented by Abraham it must be rendered, 'God caused me to depart'. Now it is because the factual knowledge that existed initially with the Lord, and also the rational concepts formed from that knowledge, were human - steeped as they were in what had been inherited from the mother - and so were not purely Divine, that they are represented by 'Abraham's' first state. But how far representations go, see 665, 1097 (end), 1361, 1992.
