Job 41:30-32

Revised Standard Version

³⁰ His underparts are like sharp potsherds;
    he spreads himself like a threshing sledge on the mire.
³¹ He makes the deep boil like a pot;
    he makes the sea like a pot of ointment.
³² Behind him he leaves a shining wake;
    one would think the deep to be hoary.
