Malachi 3:8-10

3:8 Can a person rob God? You indeed are robbing me, but you say, ‘How are we robbing you?’ In tithes and contributions! 3:9 You are bound for judgment because you are robbing me – this whole nation is guilty.

3:10 “Bring the entire tithe into the storehouse so that there may be food in my temple. Test me in this matter,” says the Lord who rules over all, “to see if I will not open for you the windows of heaven and pour out for you a blessing until there is no room for it all.
