Translation:Are you willing to defend me?
Klingon doesn't have a noun case for this sort of "from." Instead, you need to include a phrase or sentence that conveys the meaning. For example: muHIvchugh jaghpu'wI', choHubqang'a' If my enemies attack me, are you willing to defend me?
The phrase or sentence needn't be quite so on the nose as that. law' jaghpu'wI'. choHubqang'a'? My enemies are many. Are you willing to defend me?
You just need to specify the thought behind from my enemies.
