I meant to stay off of Wattpad since I have an essay due Friday and can't work on it for half of the following three days.

I'm totally stuck, though; I can't understand this one specific sentence.

I need to understand it so that I can actually use it in my essay without misusing it. ;^;

"...while the black slave was free with the security of the useful horse, mule, cow, goat, or dog whose life and health is worth money to the owner."

I searched it up and got no hints. Is anyone able to help? ;^;

Sorry for relying on y'all, but I don't exactly want to waste my mom's money asking my cousin (and I can't ask my teacher)...
