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.
Daniel 4:10-16
10
Thus were the visions of my head on my bed: I saw, and behold, a tree in the midst of the earth; and its height was great.
11
The tree grew, and was strong, and its height reached to the sky, and its sight to the end of all the earth.
12
The leaves of it were beautiful, and its fruit much, and in it was food for all: the animals of the field had shadow under it, and the birds of the sky lived in its branches, and all flesh was fed from it.
13
I saw in the visions of my head on my bed, and behold, a watcher and a holy one came down from the sky.
14
He cried aloud, and said thus, Cut down the tree, and cut off its branches, shake off its leaves, and scatter its fruit: let the animals get away from under it, and the fowls from its branches.
15
Nevertheless leave the stump of its roots in the earth, even with a band of iron and brass, in the tender grass of the field; and let it be wet with the dew of the sky: and let his portion be with the animals in the grass of the earth:
16
let his heart be changed from man's, and let an animal's heart be given to him; and let seven times pass over him.
