Study Lenses
The verse centers on "seven", "priests", "bearing", "trumpets", "jubilee", "before", and "jehovah". It is saying that the verse draws attention to "seven" and "priests", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 12's "And Joshua riseth early in the morning..." into verse 14's "And they compass the city on the...", so "seven" and "priests" belong inside that flow. In Joshua context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "seven" and "priests" with trust shaped by these words, not by a vague optimism outside the passage.
