The movies change it based on what creates tension or is funny in the current situation.
In X-Men the Last Stand he is able to survive disintegration that goes through people around him in about a second by constantly healing the damage back (and his pants repair themselves too I guess). And a similar thing happens when he survives a nuclear bomb in the Wolverine. In Origins: Wolverine he is able to heal back from an adamantium bullet to the head fairly quickly but loses his memories.
Deadpool is supposed to have a stronger healing factor but it still takes something like hours to a day for his hand to finish growing back after it gets cut off in his movie.
I doubt the comics are much better about being consistent with the amount of retcons and changing writers that happen.


Yeah, I don't think it really matters what word is considered a better translation. It is talking about humans becoming property.
In Exodus 21:2-11, it says Hebrew men are restricted to being indentured servants for 6 years unless they volunteer for more. And Hebrew girls/women are sold forever, just not to foreign nations. And in Leviticus 25:44-46, it directly addresses that gentiles can be enslaved, sold, and inherited with no special restrictions.
A slave by another name is still a slave.
