Job 18:8 - Joseph Benson’s Commentary on the Old and New Testaments

He is cast into a net by his own feet By his own choice, design, and actions. And he walketh upon a snare Or, as the words may be rendered, runneth to and fro on the toils, and therefore must needs be entangled and destroyed. “The metaphor” says Heath, “is taken from a beast, which the hunters have driven into the toils. He runs hither and thither, striving to find a way out, but the net entangles him more and more, till at length it fastens upon him.”
