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.

7719. 'And all the children of Israel had light in their dwellings' means that those belonging to the spiritual Church had enlightenment throughout their mind. This is clear from the representation of 'the children of Israel' as those belonging to the spiritual Church, dealt with in 6426, 6637, 6862, 6868, 7035, 7062, 7198, 7201, 7215, 7223; from the meaning of 'light' as enlightenment, for light flowing from the Lord enlightens the understanding since that light holds intelligence and wisdom within it, see 1521, 1524, 1619-1632, 2776, 3138, 3167, 3190, 3195, 3222, 3123, 3339, 3636, 3643, 3997, 4302, 4408, from the meaning of 'dwellings' as parts of the mind. For 'house' means the human mind, 3538, 4973, 5023, 7353, and 'rooms' its inner parts, 7353; but 'dwellings' means all the parts of the mind. Furthermore 'dwelling in' means in the internal sense living, 1293, 3384, 3613, 4451, 60511 and therefore 'dwellings' are parts in which the elements of life reside, namely aspects of intelligence and wisdom, which - as is well known - belong to the mind. Also, in the next life, the exact nature of the light shining in angels' dwellings or habitations is determined by the intelligence and wisdom present in the angels' minds. And in the same measure that they have light, those who are their opposites, that is, those who engage in molestation, have thick darkness.
