Okay, I'll just come right out and ask the question: Isn't that a bit violent?
Not at all. When animals attack, even each other, there is no such thing as being to violent.
When you get a chance, look at youtube for "lion break young lions spine" or "tiger attack man on the elephant." You will see that when predators attack they don't have those kind of sensibilities. Further, there is a mitzvah in the Torah for people to protect their lives. We Jews have a concept that we are supposed to live in the mitzvot and not die in them.
Couldn't Samson have just punched the lion and knocked it out with his super strength? Also, I don't know what Hebrew word or concept that Jews use for 'spirit of the lord' but could 'it' have guided Samson with a more humane way of stopping this wild animal?
In terms of punching a lion and knocking it out. The Torath Mosheh concept is that Shimshon was not the image you may be used to from the Christian concept. See my coment in the next response below.
I have listed to a few accounts of people who have been charged or attacked by bears, mountain lions, etc. and none of them see to have a problem with protecting themelves, which often requires killing the attacking, with whatever mean necessary. This is in a time when there is the possibilities of guns and even wildlife protection services.
The following are examples of people who had to kill animals that were attacking them. None of them did so in a nice way.
Also, I don't know what Hebrew word or concept that Jews use for 'spirit of the lord' but could 'it' have guided Samson with a more humane way of stopping this wild animal?
In Hebrew it is called (רוח ה). It is like saying that Shimshon received the know how, endurance, and ability that was humanly available to him personally to overcome the situation he was in.
All of this was already built into the system of reality for Shimshon at the appropriate times. I would not call it super strength in the super hero because there are normal people all the time who display almost superhuman ability to overcome a challenge or do something the average person can't.do. In a way no different than I would call a surge of adrelanine with the knowledge how to properly use it something beyond the possibility of humanity.
This discription of how James Shaw handled the Waffle House attacker is an example of what we mean but amplified just a bit more.
Look it up on YouTube "
