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.

3035. 'Jehovah, the God of heaven' means the Lord's Divine itself. This is clear from what has been stated above in 3023 - that 'Jehovah, the God of heaven' is the Lord's Divine itself, for the name 'Jehovah', which occurs so many times in the Old Testament Word, was used to mean the Lord alone. Every single detail there refers in the internal sense to Him, and every single religious observance of the Church represented Him, see 1736, 2921. Furthermore the most ancient people who belonged to the celestial Church did not mean by 'Jehovah' anyone other than the Lord, 1343. Here and elsewhere in the sense of the letter it seems as though someone other, who is higher, is meant by Jehovah; but the sense of the letter is such that it sets forth as separate entities things which the internal sense presents as one. The reason for this is that man who has to be taught from the sense of the letter is unable to have the idea of one without first of all having the idea of several. For with man that which is a single whole is formed from several parts, or what amounts to the same, things existing simultaneously come into being consecutively. Many attributes exist in the Lord, and all are Jehovah, and therefore the sense of the letter regards these as separate entities, whereas heaven never does so. Heaven acknowledges one God with an idea that does not divide Him; nor does it acknowledge anyone other than the Lord.
