Malachi 3:6-10

For I, the LORD, do not change, and you, sons of Jacob, do not cease to be. Since the days of your ancestors you have turned aside from my statutes and have not kept them. Return to me, that I may return to you, says the LORD of hosts. But you say, “Why should we return?” Can anyone rob God? But you are robbing me! And you say, “How have we robbed you?” Of tithes and contributions! You are indeed accursed, for you, the whole nation, rob me. Bring the whole tithe into the storehouse, That there may be food in my house. Put me to the test, says the LORD of hosts, And see if I do not open the floodgates of heaven for you, and pour down upon you blessing without measure!
