Marriages among people – both in the Bible and in life – represent spiritual marriage. Women represent the desire to be good and to do good things; men represent the understanding of how to be good and how to do good things. Each one of us, male or female, can experience that marriage within us if we work to learn about the Lord and dedicate ourselves to doing His will. And just as natural marriages produce children, so do spiritual marriages. Daughters represent affections, the emotional response we have to good things and positive ideas. Sons represent those positive ideas, facts and knowledge leading to a greater understanding. This makes sense if you think about it. If in life you’re working to be a good person and thinking about how to do that, finding a nugget of wisdom in the Word – or from another source – is a joyful thing. Finding a way to be good to someone and serve them is a joyful thing as well (it helps if they appreciate it, but that’s not really the point). That joy, that affection for what is true and what is good, is a "daughter." On a broader level, daughters also sometimes represent churches, since churches are based on an affection for truth. And as with all representations, the meaning of "daughter" can also be reversed, representing the thrill of evil.

In Psalm 45:9, this signifies a church from goods. (Arcana Coelestia 490)

In Genesis 20:12, this signifies the rational, conceived of celestial good as a father, but not of spiritual truth as a mother. (Arcana Coelestia 2557)

Korah was a man of the tribe of Levi, who together with Dathan and Abiram, led an insurrection against Moses and Aaron. Apparently their insurrection was prompted by their being out in the wilderness with no place to go. This happened after the Children of Israel had approached the land of Canaan from the south and had sent out spies to scout the land. Ten of the twelve spies said the land was too strong for them, that there were giants there. Moses then told the whole congregation they would all have to spend forty years in the wilderness until all that generation had died. In this story, Moses and Aaron represent the Lord. When Korah and his fellow rebels murmured against them and took fire from the altar and burned incense with it, they represented the profanation of mixing what is good (the fire from the altar) with what is evil (rebelling against Moses). The three rebel leaders and their followers were separated from the congregation and were swallowed up by a pit that opened in the earth. In our lives, evils need to be separated, too, and gotten rid of.
