There is only one place in the Bible that the Lord God invited us to prove Him. And it involved “tithes” or in contemporary language, it involved money. Nevertheless, the focus is not so much on the money but on the underlining principle.
The Lord dared Israel:
“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”, (Malachi 3:10).
