And tread down the wicked in their place - Even in the very place where they are, crush them to the dust, as God can. It is implied that God was able to do this, and he appeals to it as a proof of his power.

Look on everyone that is proud, and bring him low,.... As the Lord often does; see Isaiah 2:11; this is the same as before;
and tread down the wicked in their place; the same with the proud, for pride makes men wicked; it is a sin, and very odious in the sight of God, and is highly resented by him; he resists the proud: now Job is bid, when he has brought proud men low, and laid their honour in the dust, to keep them there, to trample upon them, and tread them as mire in the street; and that in their own place, or wherever he should find them; the Septuagint render it "immediately"; see Isaiah 28:3.

proud--high (Daniel 4:37).
in their place--on the spot; suddenly, before they can move from their place. (See on Job 34:26; Job 36:20).
