'Son' 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 they shall be unto me a peculiar treasure, saith Jehovah of hosts, in the day that I prepare; and I will spare them as a man spareth his own son that serveth him.
