Don't get me wrong it IS different. But not vastly so. I.e., no employer is laying a hand on you to discipline you when you do something wrong or are a terrible employee. Whereas a master in the bible is allowed to beat the slave.
But the bible has very strict rules about how slaves are treated. Since I'm posting again I'll include why the awl throuh the ear bit isn't as bad as it sounds. A slave WHO CAME WITH his wife took his wife when he left. The only time the master kept the wife and kids is when he was the one who provided the wife, and the slave didn't bring his wife originally. So, there is a huge difference here that isn't explained at all in that article. This tells me there are likely many other things they either left out on purpose, or missed because they are ignorant.
also it should be pointed out that though the master COULD keep the wife and kids, that doesn't mean he always did. This was a guideline, a law showing the masters rights but that didn't mean this is how they ALWAYS chose to proceed.
