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.

6904. 'And now let us go, we beg you, a way of three days into the wilderness' means a life of truth in a state totally removed from falsities, even though it is led in a state of obscurity. This is clear from the meaning of 'going' as leading a life, dealt with in 3335, 4882, 5493, 5605; from the meaning of 'a way' as truth, dealt with in 627, 2333; from the meaning of 'three days' as a complete state, dealt with in 2788, 4495, so that when the expression is used in connection with being removed from falsities, it describes a state totally removed from them ('putting a journey of three days between' is a total setting apart, see 4010); and from the meaning of 'the wilderness' as that which is uninhabited and uncultivated, dealt with in 2708, 3900. Which in the spiritual sense is obscurity of faith. For the subject here is the establishment of the spiritual Church, which is meant by 'the children of Israel'; and those who belong to that Church are in comparative obscurity so far as the good and truth of faith are concerned, see 2708, 2715, 2716, 2718, 2831, 2849, 2975, 2937, 3141, 3246, 3837, 4402, 6289, 6500, 6865. A life of truth is the life that is led by those who belong to the spiritual Church; for when the truth that they know from the Word or from the teaching of the Church becomes a matter of life it is called good, yet it is truth expressed in action.
