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 31:10-18
10
Therefore thus said the Lord Yahweh: Because you are exalted in stature, and he has set his top among the thick boughs, and his heart is lifted up in his height;
11
I will even deliver him into the hand of the mighty one of the nations; he shall surely deal with him; I have driven him out for his wickedness.
12
Strangers, the terrible of the nations, have cut him off, and have left him: on the mountains and in all the valleys his branches are fallen, and his boughs are broken by all the watercourses of the land; and all the peoples of the earth are gone down from his shadow, and have left him.
13
On his ruin all the birds of the sky shall dwell, and all the animals of the field shall be on his branches;
14
to the end that none of all the trees by the waters exalt themselves in their stature, neither set their top among the thick boughs, nor that their mighty ones stand up on their height, [even] all who drink water: for they are all delivered to death, to the lower parts of the earth, in the midst of the children of men, with those who go down to the pit.
15
Thus says the Lord Yahweh: In the day when he went down to Sheol I caused a mourning: I covered the deep for him, and I restrained its rivers; and the great waters were stayed; and I caused Lebanon to mourn for him, and all the trees of the field fainted for him.
16
I made the nations to shake at the sound of his fall, when I cast him down to Sheol with those who descend into the pit; and all the trees of Eden, the choice and best of Lebanon, all that drink water, were comforted in the lower parts of the earth.
17
They also went down into Sheol with him to those who are slain by the sword; yes, those who were his arm, [that] lived under his shadow in the midst of the nations.
18
To whom are you thus like in glory and in greatness among the trees of Eden? yet you will be brought down with the trees of Eden to the lower parts of the earth: you shall lie in the midst of the uncircumcised, with those who are slain by the sword. This is Pharaoh and all his multitude, says the Lord Yahweh.
