Joshua 1:7

Remember that though thou art the captain and commander of my people, yet thou art my subject, and obliged to observe all my commands. To the right hand or to the left, i.e. in any kind, or upon any pretence. That thou mayest prosper, or, that thou mayest do wisely; whereby he instructs him in the true art of government; and that his greatest wisdom will lie in the observation of all God's commands. and not in that pretended reason of state which other princes govern all their affairs by. And this plainly shows that God's assistance promised to him and to the Israelites was conditional, and might justly be withdrawn upon their breach of the conditions. Whithersoever thou goest, i.e. whatsoever thou doest. Men's actions are oft compared to ways, or journeys, or steps, by which they come to the end they aim at.
