Study Lenses
The verse centers on "hath", "been", "things", "come", "upon", "thee", "blessing", and "reviling". It is saying that the verse draws attention to "hath" and "been", so its meaning should be read from those terms before moving to application.
The next verse adds "and hast turned back unto Jehovah thy...", so "hath" and "been" should be read forward into that movement. In Deuteronomy context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "hath" and "been" with trust shaped by these words, not by a vague optimism outside the passage.
