Go through the midst of the camp, and command the people, saying, Prepare yourselves victuals, for in three days ye shall pass over this Jordan, that ye may enter in to take possession of the land which Jehovah your God giveth you to possess it.
Joshua 1:9 Have I not commanded thee: Be strong and courageous? Be not afraid, neither be dismayed; for Jehovah thy God is with thee whithersoever thou goest.
Joshua 1:10 And Joshua commanded the officers of the people, saying,
Joshua 1:11 Go through the midst of the camp, and command the people, saying, Prepare yourselves victuals, for in three days ye shall pass over this Jordan, that ye may enter in to take possession of the land which Jehovah your God giveth you to possess it.
Joshua 1:12 And to the Reubenites and to the Gadites and to half the tribe of Manasseh spoke Joshua, saying,
Joshua 1:13 Remember the word that Moses the servant of Jehovah commanded you, saying, Jehovah your God has given you rest and has given you this land.
The verse centers on "through", "midst", "camp", "command", "people", "saying", "prepare", and "yourselves". It is saying that the verse draws attention to "through" and "midst", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 10's "And Joshua commanded the officers of the..." into verse 12's "And to the Reubenites and to the...", so "through" and "midst" 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 "through" and "midst" with trust shaped by these words, not by a vague optimism outside the passage.
