'Servant' in the Bible

A son gives honour to his father, and a servant has fear of his master: if then I am a father, where is my honour? and if I am a master, where is the fear of me? says the Lord of armies to you, O priests, who give no value to my name. And you say, How have we not given value to your name?

For it is right for the priest's lips to keep knowledge, and for men to be waiting for the law from his mouth: for he is the servant sent from the Lord of armies.

See, I am sending my servant, and he will make ready the way before me; and the Lord, whom you are looking for, will suddenly come to his Temple; and the angel of the agreement, in whom you have delight, see, he is coming, says the Lord of armies.

And I will come near to you for judging; I will quickly be a witness against the wonder-workers, against those who have been untrue in married life, against those who take false oaths; against those who keep back from the servant his payment, and who are hard on the widow and the child without a father, who do not give his rights to the man from a strange country, and have no fear of me, says the Lord of armies.

And they will be mine, says the Lord, in the day when I make them my special property; and I will have mercy on them as a man has mercy on his son who is his servant.

Then you will again see how the upright man is different from the sinner, and the servant of God from him who is not.

Keep in mind the law of Moses, my servant, which I gave him in Horeb for all Israel, even the rules and the decisions.
