Malachi 3:6-9

6For I am the Lord, I change not; therefore ye sons of Jacob are not consumed.

7Even from the days of your fathers ye are gone away from mine ordinances, and have not kept them. Return unto me, and I will return unto you, saith the Lord of hosts. But ye said, Wherein shall we return?

8Will a man rob God? Yet ye have robbed me. But ye say, Wherein have we robbed thee? In tithes and offerings. 9Ye are cursed with a curse: for ye have robbed me, even this whole nation.
