Malachi 3:7-10

Since the time of your ancestors, you have disobeyed my rules and have not kept them. 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. Bring to the storehouse a full tenth of what you earn so there will be food in my house. Test me in this,” says the LORD All-Powerful. “I will open the windows of heaven for you and pour out all the blessings you need.
