For I am the Lord, and I change not: and you the sons of Jacob are not consumed. For from the days of your fathers you have departed from my ordinances, and have not kept them: Return to me, and I will return to you, saith the Lord of hosts. And you have said: Wherein shall we return? Shall a man afflict God? for you afflict me. And you have said: Wherein do we afflict thee? in tithes and in firstfruits. And you are cursed with want, and you afflict me, even the whole nation of you. Bring all the tithes into the storehouse, that there may be meat in my house, and try me in this, saith the Lord: if I open not unto you the flood-gates of heaven, and pour you out a blessing even to abundance.
Malachi chapter 3 verse 6
