Malachi 3:7-10

“Yet from the days of your fathers you have turned away from My statutes and ordinances 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, ‘In what way have we robbed You?’ In tithes and offerings [you have withheld]. You are cursed with a curse, for you are robbing Me, this whole nation! [Lev 26:14-17] Bring all the tithes (the tenth) 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 [so great] a blessing until there is no more room to receive it. [Mal 2:2]
