Study Lenses
The verse centers on "remove", "cometh", "north", "drive", "land", "barren", "desolate", and "face". It is saying that the verse draws attention to "remove" and "cometh", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 19's "And Jehovah will answer and say unto..." into verse 21's "Fear not O land be glad and...", so "remove" and "cometh" 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 "remove" and "cometh" with trust shaped by these words, not by a vague optimism outside the passage.
