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.

8510. 'That some of the people went out to gather, and did not find' means that they wished to acquire it, but none was given. This is clear from the explanation above in 8505. The explanation there shows what actions springing from the truth of faith are and what those springing from the good of charity are. That is to say, it shows that a person whose actions spring from the truth of faith does not as yet have the order of heaven present in himself, whereas one whose actions spring from the good of charity does have it. For, according to order, when the Lord leads a person He does so through his will, consequently through good since this belongs properly to the will. In that case his understanding is subservient, and so is truth since this belongs properly to the understanding. When this state exists it is the sabbath, for then there is rest for the Lord; and the state comes into being once good has been joined to truth. That this state is the Lord's rest may be recognized from the statement that after six days of creation and labour Jehovah or the Lord rested on the seventh day from all His work, Genesis 2:2. This state is heaven's state, which explains why heaven itself is called the sabbath, and that in heaven the sabbath is perpetual. For the creation story in Genesis 1 serves to mean the new creation, which is regeneration, and the six days in the story serves to mean temptations and conflicts, see the explanations at Genesis 1, 2.
