Translation of "servant" into Persian

I am the good and faithful servant who brings water in the desert

خوب و وفادار هستم که من همان بنده درصحرا آب بوجود آورد

i was still little better than a servant. still not to be trusted

من هنوز بهتر از يک نوكر بودم ولي نه قابل اعتماد

Vronsky told the servant not to announce him, and slipped quietly into the first room.

ورانسکی به خدمتکار گفت که ورودش را اعلام نکند و بی صدا به داخل سرسرا سرید.
