1. The prophet here acknowledges the sovereignty and dominion of the divine Providence, that by it, and not by their own will and wisdom, the affairs both of nations and particular persons are directed and determined, v. 23. This is an article of our faith which it is very proper for us to make confession of at the throne of grace when we are complaining of an affliction or suing for a mercy: "O Lord, I know, and believe, that the way of man is not in himself; Nebuchadnezzar did not come of himself against our land, but by the direction of a divine Providence." We cannot of ourselves do any thing for our own relief, unless God work with us and command deliverance for us; for it is not in man that walketh to direct his steps, though he seem in his walking to be perfectly at liberty and to choose his own way. Those that had promised themselves a long enjoyment of their estates and possessions were made to know, by sad experience, when they were thrown out by the Chaldeans, that the way of man is not in himself; he designs which men lay deep, and think well-formed, are dashed to pieces in a moment. We must all apply this to ourselves, and mix faith with it, that we are not at our own disposal, but under a divine direction; the event is often overruled so as to be quite contrary to our intention and expectation. We are not masters of our own way, nor can we think that every thing should be according to our mind; we must therefore refer ourselves to God and acquiesce in his will. Some think that the prophet here mentions this with a design to make this comfortable use of it, that, the way of the Chaldean army being not in themselves, they can do no more than God permits them; he can set bounds to these proud waves, and say, Hitherto they shall come, and no further. And a quieting consideration it is that the most formidable enemies have no power against us but what is given them from above.
