Six
Like most numbers in the Bible, "six" can have various meanings depending on context, but has a couple that are primary. When used in relation to time -- six days, six hours, six years, etc. -- six generally represents a state of labor, struggle and conflict, especially the conflict involved with spiritual growth. The six days of creation, for instance, represent the stages we go through in our lives, working toward the peaceful seventh day, in which our evil desires are removed from us and we can rest. In most other references, six represents all desires for good and all the true ideas that come from those desires for good -- or in the contrary sense, all evil and all the resulting false thinking.
Arcana Coelestia #1552
1552. 'And gold' means goods deriving from truths. This is clear from the meaning of 'gold' as celestial good, or the good of wisdom and love, as is clear from what has just been shown and also from what was shown previously in 113. That here they are goods deriving from truths follows from what was stated in the previous chapter about the Lord's joining intellectual truths to celestial things.
