'Servant' in the Bible

Pharaoh’s daughter went down to bathe at the Nile while her servant girls walked along the riverbank. Seeing the basket among the reeds, she sent her slave girl to get it.

But Moses replied to the Lord, “Please, Lord, I have never been eloquent—either in the past or recently or since You have been speaking to Your servant—because I am slow and hesitant in speech.”

and every firstborn male in the land of Egypt will die, from the firstborn of Pharaoh who sits on his throne to the firstborn of the servant girl who is behind the millstones, as well as every firstborn of the livestock.

When Israel saw the great power that the Lord used against the Egyptians, the people feared the Lord and believed in Him and in His servant Moses.
