Then thou shalt say before the Lord thy God, I have brought away the HALLOWED THINGS out of mine house, and also have given them unto the LEVITE, and unto the STRANGER, to the FATHERLESS, and to the WIDOW, according to all thy commandments which thou hast commanded me: I have not transgressed thy commandments, neither have I forgotten them: Look down from thy holy habitation, from heaven, and BLESS THY PEOPLE ISRAEL, and the land which thou hast given us, as thou swarest unto our fathers, a land that floweth with milk and honey. And the Lord hath AVOUCHED thee this day to be his peculiar people, as he hath promised thee, and that thou shouldest keep all his commandments; And to make thee high above all nations which he hath made, in praise, and in name, and in honour; and that thou mayest be an holy people unto the Lord thy God, as he hath spoken. – Deuteronomy 26:13, 15-15, 18-19 KJV
Bring ye all the tithes into the storehouse, that there may be meat in mine house, and prove me now herewith, saith the Lord of hosts, if I will not open you the windows of heaven, and pour you out a blessing, that there shall not be room enough to receive it. And I will rebuke the devourer for your sakes, and he shall not destroy the fruits of your ground; neither shall your vine cast her fruit before the time in the field, saith the Lord of hosts. And all nations shall call you blessed: for ye shall be a delightsome land, saith the Lord of hosts. –Malachi 3:10-12 KJV.
