Job 18:7

The steps of his strength shall be straitened,.... As a man in health can take large and strong steps, and travel in the greatness of his strength; so in prosperity he can and does take large steps in obtaining fame and reputation among men, in amassing substance to himself, and towards settling his family in the world; he is like one in a large place, and walks at liberty, goes in and out at pleasure, and none can control him; he walks in pride, and with an high and lifted up head, and with contempt of others, and his will is his law, and he does as he pleases; but in adversity, as his strength is weakened in the way, he cannot take the strides he did, his way is hedged up with thorns, he is pressed on every side, and surrounded with troubles, so that, let him turn himself which way he will, he can find no way to escape:

and his own counsel shall cast him down; as Ahithophel's and Haman's did, which issued in their ruin, 2 Samuel 17:23; what wicked men sometimes plot and devise, with a view to their own good, and the injury of others, proves the destruction of themselves; when they have contrived to raise themselves upon the ruins of others, it has been the means of casting them down from the state and condition they were in, instead of raising to an higher, even down to desolation, and into the most miserable circumstances.
