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.
Bring all your offerings to the church so there's food in God's house. Then, God challenges you, "I will pour blessings on you from heaven so much that you won't have enough space to hold them."
