Malachi 3:6-12 New Revised Standard Version (NRSV)
6 For I the Lord do not change; therefore you, O children of Jacob, have not perished. 7 Ever since the days of your ancestors you have turned aside from my statutes 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?”
Do Not Rob God
8 Will anyone rob God? Yet you are robbing me! But you say, “How are we robbing you?” In your tithes and offerings! 9 You are cursed with a curse, for you are robbing me—the whole nation of you! 10 Bring the full tithe into the storehouse, so that there may be food in my house, and thus put me to the test, says the Lord of hosts; see if I will not open the windows of heaven for you and pour down for you an overflowing blessing. 11 I will rebuke the locust[a] for you, so that it will not destroy the produce of your soil; and your vine in the field shall not be barren, says the Lord of hosts. 12 Then all nations will count you happy, for you will be a land of delight, says the Lord of hosts.
