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 # 7382
7382. 'Stretch out your hand with your rod' means the power of inward truth directed through outward truth. This is clear from the meaning of 'hand' as spiritual power, which belongs to inward truth, and from the representation of 'rod' as natural power, which belongs to outward truth, both dealt with in 6947, 6948. For the fact that all power in the spiritual world belongs to truth, see 3091, 3787, 4931, 6344, 6423, 6948. Since 'Moses' represents inward law, which is the same as inward truth, and 'Aaron' represents outward law, which is the same as outward truth, and since inward truth flows into outward truth and gives it power, 7381, Moses' word of command to Aaron 'stretch out your hand with your rod' means the power of inward truth directed through outward truth.
