'Man' in the Bible

Have we not all one father? Hath not one God created us? Why do we deal unfaithfully every man against his brother, by profaning the covenant of our fathers?

Jehovah will cut off from the tents of Jacob the man that doeth this, him that calleth and him that answereth; and him that offereth an oblation unto Jehovah of hosts.

Will a man rob God? But ye rob me. And ye say, Wherein do we rob thee? In tithes and heave-offerings.

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.
