Malachi 3:7-9

Return to me, and I will return to you,” says the LORD All-Powerful. “But you ask, ‘How can we return?’ “Should a person rob God? But you are robbing me. “You ask, ‘How have we robbed you?’ “You have robbed me in your offerings and the tenth of your crops. So a curse is on you, because the whole nation has robbed me.
