Joshua 1:8-9

8This Book of the Law shall not depart from your mouth, but you shall read [and meditate on] it day and night, so that you may be careful to do [everything] in accordance with all that is written in it; for then you will make your way prosperous, and then you will be successful.

9Have I not commanded you? Be strong and courageous! Do not be terrified or dismayed (intimidated), for the Lord your God is with you wherever you go.”
