'Servant' in the Bible

A son honoureth his father, and a servant his master: if then I be a father, where is mine honour? and if I be a master, where is my fear? saith Jehovah of hosts unto you, priests, that despise my name. But ye say, Wherein have we despised thy name?

And I will come near to you to judgment; and I will be a swift witness against the sorcerers, and against the adulterers, and against the false swearers, and against those that oppress the hired servant in his wages, the widow and the fatherless, and that turn aside the stranger from his right, and fear not me, saith Jehovah of hosts.

Remember the law of Moses my servant, which I commanded unto him in Horeb for all Israel, the statutes and ordinances.
