⁷ Only be strong and very courageous, being careful to act in accordance with all the law that my servant Moses commanded you; do not turn from it to the right hand or to the left, so that you may be successful wherever you go.^{(A) 8} This book of the law shall not depart out of your mouth; you shall meditate on it day and night, so that you may be careful to act in accordance with all that is written in it. For then you shall make your way prosperous, and then you shall be successful.^{(B) 9} I hereby command you: Be strong and courageous; do not be frightened or dismayed, for the Lord your God is with you wherever you go.”^(C)

¹⁴ But as for you, continue in what you have learned and firmly believed, knowing from whom you learned it ¹⁵ and how from childhood you have known sacred writings that are able to instruct you for salvation through faith in Christ Jesus. ¹⁶ All scripture is inspired by God and is^[a] useful for teaching, for reproof, for correction, and for training in righteousness,^{(A) 17} so that the person of God may be proficient, equipped for every good work.^(B)
