Malachi 3:8-10

“Will a man rob God? For you are robbing Me!” But you say: “How have we robbed You?” “In the tithe and the offering. You have been cursed with the curse, yet you keep robbing Me—the whole nation! Bring the whole tithe into the storehouse. Then there will be food in My House. Now test Me in this”—says ADONAI-Tzva’ot—“if I will not open for you the windows of heaven, and pour out blessing for you, until no one is without enough.
