House
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.
Arcana Coelestia #7598
7598. '[In order] that you may know that the earth is Jehovah's' means that from this it may be recognized that the Lord is the only God of the Church. This is clear from the meaning of 'knowing' as its being recognized; and from the meaning of 'the earth' as the Church, dealt with in 662, 1066, 1067, 1262, 1413, 1607, 1733, 1850, 4447, 4535, 5577 - 'Jehovah' being the Lord, see 1343, 1736, 2921, 3023, 3035, 5663, 6303, 6905, 6945, 6956. From this it is evident that 'the earth is Jehovah's' means that the Church is the Lord's, thus that the Lord is the only God of the Church, as in 7401, 7444, 7544.
