Malachi 3:6-10

For I am the LORD, I have not changed; therefore, ye sons of Jacob have not been consumed. ¶ Even from the days of your fathers, ye had departed from my ordinances and had never kept them. Return unto me, and I will return unto you, said the LORD of the hosts. But ye said, In what shall we return? Will a man rob God? Yet ye have robbed me. But ye say, In what have we robbed thee? In the tithes and the offerings. Ye are cursed with a curse: for ye, even this whole nation, have robbed me. Bring ye all the tithes into the storehouse, and there shall be food in my house, and prove me now in this, said the LORD of the hosts, if I will not open you the windows of heaven and pour you out a blessing that there shall not be room enough to receive it.
