As in live by the sword, die by the sword, what goes around, comes around, you reap what you sow?
If those who “live by the sword, die by the sword” as Jesus said, then it seems to me that someone must pick up the sword to cause this to happen.
This was something I put forth in the discussions I got into regarding the Iraq war. I felt that the coalition forces were appointed to take care of Saddam Hussein. He lived by the sword, and someone had to carry out his dying by the sword.
you get what you give, etc. etc.
