'Servant of the Lord' in the Bible

So Moses the servant of the Lord died there in the land of Moab, as the Lord had said.

Joshua son of Nun, the servant of the Lord, died at the age of 110.

because they did not listen to the voice of the Lord their God but violated His covenant—all He had commanded Moses the servant of the Lord. They did not listen, and they did not obey.

Who is blind but My servant,or deaf like My messenger I am sending?Who is blind like My dedicated one,or blind like the servant of the Lord?
