Malachi 3:6-10

“For I, the LORD, do not change; therefore you, O sons of Jacob, are not consumed. “From the days of your fathers you have turned aside from My statutes and have not kept them. Return to Me, and I will return to you,” says the LORD of hosts. “But you say, ‘How shall we return?’ “Will a man rob God? Yet you are robbing Me! But you say, ‘How have we robbed You?’ In tithes and offerings. You are cursed with a curse, for you are robbing Me, the whole nation of you! Bring the whole tithe into the storehouse, so that there may be food in My house, and test Me now in this,” says the LORD of hosts, “if I will not open for you the windows of heaven and pour out for you a blessing until it overflows.
