What is the verb meaning of "wind" in "You wound me"?

"Why, Jaime, my sweet brother," he said,"You wound me. You know how much I love my family."

This sentence is extracted from the Game of Thrones. I have looked up the dictionary but still don't understand the verb meaning of "wind". Whether it means Jamie misunderstands Tyrion or Jamie make Tyrion confused? I think both of the two understandings state show a meaning of turning or twisting.

In this context, "wound" is not the past tense of wind (as in to "wind up a clock", nor as in "the wind blows"). It is instead the verb form of the noun "wound", meaning an injury of some description.

To wound someone is to cause them a wound (injury). From the Macquarie dictionary—yes, I'm Australian but it's usually closer to "real" English than most US dictionaries :-) :

wound /wund/ … noun an injury to an organism, usually one involving division of tissue … verb to inflict a wound upon.

Also in the context of the quote (assuming you've read the books or seen the TV show), this wound has nothing to do with an actual physical injury; it's more of an emotional wound because Jaime Lannister said something hurtful to his brother.
