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.

10117. 'Because it is holy' means what is Divine, to which it must not be joined, because that would result in profanation. This is clear from the meaning of 'holy' as that which is Divine, dealt with above in 10111. The reason why it must not be joined to what is Divine is that 'any of the flesh and bread that is left' means that which has not been joined, 10114, and so also that which must not be joined. That which must not be joined is the human self, which is nothing other than evil, see above in 10115; and if what is Divine is joined to the human self, and so to what is evil, it is rendered profane, 6348, 9298. This is why it says, in Leviticus 19:7-8, that whoever eats what is left till morning profanes Jehovah's holy offering, and that that soul shall be cut off from his people; and also, in Leviticus 7:19, that the flesh of a sacrifice that touches any unclean thing shall be burned with fire. From this it is now evident that profaning that which is holy is meant by eating the flesh and bread of the sacrifice on the following day.
