Joshua 1:7-8

Only be strong and very bold in taking care to follow all the Torah which Moshe my servant ordered you to follow; do not turn from it either to the right or to the left; then you will succeed wherever you go.

Yes, keep this book of the Torah on your lips, and meditate on it day and night, so that you will take care to act according to everything written in it. Then your undertakings will prosper, and you will succeed.
