1:8 This book of the law shall not depart out of thy mouth; but thou shalt meditate therein day and {f} night, that thou mayest observe to do according to all that is written therein: for then thou shalt make thy way prosperous, and then thou shalt have good success.
(f) Showing that it is not possible to govern well, without the continual study of God's word.
1:8 Out of thy mouth - That is, thou shalt constantly read it, and upon occasion discourse of it, and the sentence which shall come out of thy mouth, shall in all things be given according to this rule. Day and night - That is, diligently study, and upon all occasions consider what is God's will and thy duty. The greatness of thy place and employments shall not hinder thee from this work, because this is the only rule of all thy private actions, and publick administrations.
1:5-9 Joshua is to make the law of God his rule. He is charged to meditate therein day and night, that he might understand it. Whatever affairs of this world we have to mind, we must not neglect the one thing needful. All his orders to the people, and his judgments, must be according to the law of God. Joshua must himself be under command; no man's dignity or dominion sets him above the law of God. He is to encourage himself with the promise and presence of God. Let not the sense of thine own infirmities dishearten thee; God is all-sufficient. I have commanded, called, and commissioned thee to do it, and will be sure to bear thee out in it. When we are in the way of duty, we have reason to be strong and very bold. Our Lord Jesus, as Joshua here, was borne up under his sufferings by a regard to the will of God, and the commandment from his Father.
