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.
Genesis 38:18-30
18
He said, "What pledge will I give you?" She said, "Your signet and your cord, and your staff that is in your hand." He gave them to her, and came in to her, and she conceived by him.
19
She arose, and went away, and put off her veil from her, and put on the garments of her widowhood.
20
Judah sent the young goat by the hand of his friend, the Adullamite, to receive the pledge from the woman's hand, but he didn't find her.
21
Then he asked the men of her place, saying, "Where is the prostitute, that was at Enaim by the road?" They said, "There has been no prostitute here."
22
He returned to Judah, and said, "I haven't found her; and also the men of the place said, 'There has been no prostitute here.'"
23
Judah said, "Let her keep it, lest we be shamed. Behold, I sent this young goat, and you haven't found her."
24
It happened about three months later, that it was told Judah, saying, "Tamar, your daughter-in-law, has played the prostitute; and moreover, behold, she is with child by prostitution." Judah said, "Bring her forth, and let her be burnt."
25
When she was brought forth, she sent to her father-in-law, saying, "By the man, whose these are, I am with child." She also said, "Please discern whose are these--the signet, and the cords, and the staff."
26
Judah acknowledged them, and said, "She is more righteous than I, because I didn't give her to Shelah, my son." He knew her again no more.
27
It happened in the time of her travail, that behold, twins were in her womb.
28
When she travailed, one put out a hand, and the midwife took and tied a scarlet thread on his hand, saying, "This came out first."
29
It happened, as he drew back his hand, that behold, his brother came out, and she said, "Why have you made a breach for yourself?" Therefore his name was called Perez.
30
Afterward his brother came out, that had the scarlet thread on his hand, and his name was called Zerah.
