Husband
In general, men are driven by intellect and women by affections, and because of this men in the Bible generally represent knowledge and truth and women generally represent love and the desire for good. This generally carries over into marriage, where the man's growing knowledge and understanding and the woman's desire to be good and useful are a powerful combination. In many cases in the Bible, then, "husband" refers to things of truth and understanding, much as "man" does. Magnificent things can happen in a true marriage, though, when both partners are looking to the Lord. If a husband opens his heart to his wife, it's as though she can implant her loves inside him, transforming his intellectual urges into a love of growing wise. She in turn can grow in her love of that blooming wisdom, and use it for joy in their married life and in their caring for children and others in their life. Many couples, even in heaven, stay in that state -- called "Spiritual" -- growing deeper and deeper to eternity. There is the potential, though, for the couple to be transformed: through the nurturing love of his wife the husband can pass from a love of growing wise to an actual love of wisdom itself, and the wife can be transformed from the love of her husband's wisdom into the wisdom of that love -- the actual expression of the love of the Lord they have built together. In that state -- called "Celestial" -- the husband represents love and the desire for good, and the wife represents truth and knowledge.
Ezekiel 31:2-9
2
Son of man, tell Pharaoh king of Egypt, and to his multitude: Whom are you like in your greatness?
3
Behold, the Assyrian was a cedar in Lebanon with beautiful branches, and with a forest-like shade, and of high stature; and its top was among the thick boughs.
4
The waters nourished it, the deep made it to grow: its rivers ran all around its plantation; and it sent out its channels to all the trees of the field.
5
Therefore its stature was exalted above all the trees of the field; and its boughs were multiplied, and its branches became long by reason of many waters, when it shot [them] forth.
6
All the birds of the sky made their nests in its boughs; and under its branches did all the animals of the field bring forth their young; and under its shadow lived all great nations.
7
Thus was it beautiful in its greatness, in the length of its branches; for its root was by many waters.
8
The cedars in the garden of God could not hide it; the fir trees were not like its boughs, and the plane trees were not as its branches; nor was any tree in the garden of God like it in its beauty.
9
I made it beautiful by the multitude of its branches, so that all the trees of Eden, that were in the garden of God, envied it.
