Live by the sword, die by the sword
From Wikipedia, the free encyclopedia
The proverb “Live by the sword, Die by the sword.” is a metaphorical expression meaning that to live ones life in a certain way will, in the end, effected ones destiny. While the expression literally means “if you live by violence you will die by violence” it is also used for a variety of situations which contain an element of poetic justice. For instance the proverb could be used to describe a person who drives regularly under the influence and ultimately is killed in a vehicle accident caused by their intoxication.
It is posible that the proverb comes from bible.[1]
“Then said Jesus unto him, Put up again thy sword into his place: for all they that take the sword shall perish with the sword.” (Matthew 26:52)
