Have not I commanded thee? Be strong and of a good courage; be not afraid, neither be thou dismayed: for the LORD thy God is with thee whithersoever thou goest.
God casts this as a question, Have I not commanded?, to force the weight of His own authority forward. When you trust His call and command, when you hold it firm in your conscience, nothing produces confidence like that. Follow wherever He leads.

God speaks to Joshua directly, probably in vision or dream, because though He has bound us to instituted means, He has not bound Himself to them. He can speak to hearts by other ways than our ears, and He does so here to give Joshua the greatest encouragement.

Commenting on Joshua 1:1-9
Consider who gives these commands: Jehovah Himself, the eternal I AM, faithful to His promises and able to perform them. That alone should animate you to the work. His Presence promised is enough, fear neither enemies nor your own unfitness.
