3146. 'And gave straw and fodder to the camels' means instruction in truths and goods. This is clear from the meaning of 'straw' as the truths present in the natural man, and from the meaning of 'fodder' as the goods there, dealt with above in 3114. Since these things are meant by 'straw and fodder' it therefore follows that 'giving straw and fodder' is giving instruction in truths and goods. The purpose of that freedom is this: Possessing the affection for truth and being stirred by that affection, a person may become instructed in such a way that truths are implanted deep within him - within the spiritual man or the soul - where they are joined to good, as may be seen from what has been shown regarding freedom in 2870-2893.

[2] This is the way in which faith - that is, truth which is the truth of faith made to take root; and unless it is coupled to good in the rational the truth of faith never receives any life, nor does any fruit develop from it. For everything called the fruit of faith is the fruit of that good which is the good of love and charity coming by way of truth which is the truth of faith. Unless spiritual warmth, which is the good of love, is actively present in spiritual light, which is the truth of faith, man would be like ground frozen stiff, as in wintertime, when nothing grows, let alone bears any fruit. For just as light devoid of warmth is totally unproductive, so is faith devoid of love.

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.
