And seven of them seven trumpets, which are used in the jubilee: and they went before the ark of the Lord, walking and sounding the trumpets: and the armed men went before them, and the rest of the common people followed the ark, and they blew the trumpets.
Joshua 6:11 So the ark of the Lord went about the city once a day, and returning into the camp, abode there.
Joshua 6:12 And Joshua rising before day, the priests took the ark of the Lord,
Joshua 6:13 And seven of them seven trumpets, which are used in the jubilee: and they went before the ark of the Lord, walking and sounding the trumpets: and the armed men went before them, and the rest of the common people followed the ark, and they blew the trumpets.
Joshua 6:14 And they went round about the city the second day once, and returned into the camp. So they did six days.
Joshua 6:15 But the seventh day, rising up early, they went about the city, as it was ordered, seven times.
The verse centers on "seven", "trumpets", "used", "jubilee", "went", "before", and "lord". It is saying that the verse draws attention to "seven" and "trumpets", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 12's "And Joshua rising before day the priests..." into verse 14's "And they went round about the city...", so "seven" and "trumpets" 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 "trumpets" with trust shaped by these words, not by a vague optimism outside the passage.
