Like most meanings in the Bible this can change depending on context to a meaning perverted into the opposite. Instead of a mind full of knowledge and love of the neighbor, the love can be twisted around to pride in one's own self-intelligence and lead toward evil instead of good. The elders and chief priests who sat in judgment on Jesus in Caiaphas' house show the other side of the representation. Elders are mentioned in the Bible mainly in two ways: First the elders of Israel: and second the 24 elders seated about the throne of God in Revelation. In both cases, they mean wisdom, which comes from using the truths we've learned to do what's right in our everyday lives. The elders of Israel mean the chief things of wisdom in the church called Israel. The elders mentioned in Revelation 4 mean the wisdom of the highest heavens, and by extension the whole of the heavens.

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.
