This book of the law shall not depart from your mouth, but you shall meditate on it day and night, that you may observe to do according to all that is written in it; for then you shall make your way prosperous, and then you shall have good success.
Joshua 1:6 “Be strong and courageous; for you shall cause this people to inherit the land which I swore to their fathers to give them.

Joshua 1:8 This book of the law shall not depart from your mouth, but you shall meditate on it day and night, that you may observe to do according to all that is written in it; for then you shall make your way prosperous, and then you shall have good success.

The verse centers on "book", "shall", "depart", "mouth", "meditate", "night", and "observe". It is saying that the verse draws attention to "book" and "shall", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 7's "Only be strong and very courageous Be..." into verse 9's "Haven t I commanded you Be strong...", so "book" and "shall" 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 "book" and "shall" with trust shaped by these words, not by a vague optimism outside the passage.
