7 “Only be strong and very courageous; be careful to do according to all the law which Moses My servant commanded you; do not turn from it to the right or to the left, so that you may have success wherever you go. 8 “This book of the law shall not depart from your mouth, but you shall meditate on it day and night, so that you may be careful to do according to all that is written in it; for then you will make your way prosperous, and then you will have success. 9 “Have I not commanded you? Be strong and courageous! Do not tremble or be dismayed, for the Lord your God is with you wherever you go.”
2 The things which you have heard from me in the presence of many witnesses, entrust these to faithful men who will be able to teach others also. 3 Suffer hardship with me, as a good soldier of Christ Jesus. 4 No soldier in active service entangles himself in the affairs of everyday life, so that he may please the one who enlisted him as a soldier. 5 Also if anyone competes as an athlete, he does not win the prize unless he competes according to the rules.
