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.

4669. 'Joseph' means the Lord's Spiritual [from His] Divine Human. This is clear from the representation of 'Joseph' in the highest sense as the Lord's Divine Spiritual, dealt with in 3969. It is well known in the Church that the Lord is represented by 'Joseph', for when the heavenly Joseph is spoken of, no one else is meant. But what aspect of the Lord is represented by 'Joseph' is less well known, namely the Divine Spiritual which proceeds from His Divine Human. The Divine Spiritual which proceeds from the Lord's Divine Human is the Divine Truth received from Him in heaven and in the Church; essentially the Spiritual is nothing else. The Divine Spiritual or Divine Truth is also that which is called the kingship of the Lord, as well as being that which is meant by 'Christ' or 'Messiah', see 2015 (end), 3009, 3670. This also explains why Joseph became virtually the king in Egypt - so that he might at that time represent the things which constitute the Lord's kingship.
