10. Bring ye all the tithes into the store-house, 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.
11. 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.
12. And all nations shall call you blessed: for ye shall be a delightsome land, saith the Lord of Hosts.
“Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, 20 and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age.”
Matthew 28:19-20
