The verse centers on "windows of heaven", "bring", "tithes", "storehouse", "meat", "mine", "prove", and "herewith". It is saying that the verse draws attention to "windows of heaven" and "bring", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 9's "Ye are cursed with a curse for..." into verse 11's "And I will rebuke the devourer for...", so "windows of heaven" and "bring" belong inside that flow. In Return to the LORD in Covenant Faithfulness, the local focus is covenant faithfulness, divine mercy, and judgment.
A plain takeaway is to answer the verse's own emphasis on "windows of heaven" and "bring" with trust shaped by these words, not by a vague optimism outside the passage.
