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.

2807. 'Abraham said, God will see for Himself to the animal for a burnt offering, my son' means the reply: The Divine Human will provide those who are to be sanctified. This is clear from the meaning of 'seeing to for oneself', when used in reference to God, as foreseeing and providing - for 'to see' in the internal sense nearest to the literal means to understand, 2150, 2325, whereas in the sense yet more interior it means having faith, 897, 2325, while in the highest sense it means foreseeing and providing; and also from the meaning of 'the animal for a burnt offering' as those members of the human race who are to be sanctified, dealt with just above in 2805. That 'the animal for a burnt offering' is here used to mean those who are spiritual is evident from what follows. The kinds of animals used for burnt offering and sacrifice each had a different meaning. That is to say, a lamb meant one thing, a sheep another, a kid and she-goat another, a ram and he-goat another, an ox yet another, as did a young bull and a calf. And young pigeons and turtle doves had meanings different again. It is quite clear that each kind of animal had its own meaning from the fact that it was laid down explicitly which kind were to be sacrificed on each particular day, at each particular religious festival, when atonement was being made, cleansing effected, inauguration carried out, and all other occasions. Which kinds were to be used on which occasions would never have been laid down so explicitly unless each one had possessed some specific meaning.

[2] Clearly all the religious observances or forms of external worship which existed in the Ancient Church, and subsequently in the Jewish, represented the Lord, so that the burnt offerings and sacrifices in particular represented Him since these were the chief forms of worship among the Hebrew nation. And because they represented the Lord they also at the same time represented among men those things that are the Lord's, that is to say, the celestial things of love, and the spiritual things of faith, and as a consequence of this represented the people themselves who were celestial and spiritual or who ought to have been so. This is why 'the animal' here means those who are spiritual, that is, those who belong to the Lord's spiritual Church. As regards 'God will see for Himself to the animal for a burnt offering, my son' meaning that the Divine Human will provide them, this is clear from the fact that here it is not said that 'Jehovah' will see to it but that 'God' will do so. When both of these names occur, as they do in this chapter, Jehovah is used to mean the same as 'the Father', and God the same as 'the Son', so that here the Divine Human is meant; and a further reason for the usage is that the spiritual man, whose salvation comes from the Divine Human, is the subject, see 2661, 2716.
