That which the palmerworm hath left, the locust hath eaten: and that which the locust hath left, the bruchus hath eaten: and that which the bruchus hath left, the mildew hath destroyed.
Joel 1:2 Hear this, ye old men, and give ear, all ye inhabitants of the land: did this ever happen in your days, or in the days of your fathers?

Joel 1:6 For a nation come up upon my land, strong, and without number: his teeth are like the teeth of a lion: and his cheek teeth as of a lion's whelp.
The verse centers on "palmerworm", "hath", "left", "locust", and "eaten". It is saying that the verse draws attention to "palmerworm" and "hath", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 3's "Tell ye of this to your children..." into verse 5's "Awake ye that are drunk and weep...", so "palmerworm" and "hath" belong inside that flow. In Joel context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "palmerworm" and "hath" with trust shaped by these words, not by a vague optimism outside the passage.
