Live by the sword die by the sword

In roman times this is an expression of how officers and the ruling class rule and govern people

Scripture has also mentioned this as Jesus words in Matthew 26:52--But Jesus said to him, "Put your sword in its place, for all who take the sword will perish by the sword."

If one is a political appointee and made his/her way up thru such process, then dont expect that once the ruling party steps down that a position is still available for the taking.
