'Courageous' in the Bible

Only be strong and very courageous; be careful to do [everything] in accordance with the entire law which Moses My servant commanded you; do not turn from it to the right or to the left, so that you may prosper and be successful wherever you go.

Have 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.”

Be steadfast and very determined to keep and to do everything that is written in the Book of the Law of Moses, so that you do not turn aside from it to the right or the left,
