This book of the law shall not depart out of your mouth, but you shall meditate thereon day and night, that you may observe to do according to all that is written therein: for then you shall make your way prosperous, and then you shall have good success.
Be careful that you observe to do the whole law: don't turn, don't deviate from it to the right, or to the left. This book of the law shall not depart out of thy mouth; but thou shalt meditate therein day and night, that thou mayest observe to do according to all that is written therein: for thus thou shalt make thy way prosperous, and thou shalt have good success ( Joshua 1:7-8 ).
