Job 18:8

Cast - Worn-out; old; cast-off.

For he is cast into a net - His own conduct will infallibly bring him to ruin. He shall be like a wild beast taken in a net; the more he flounces in order to extricate himself, the more he shall be entangled.

He walketh upon a snare - He is continually walking on the meshes of a net, by which he must soon be entangled and overthrown.

For he is cast into a net by his own feet - He is caught in his own tricks, as if he had spread a net or dug a pitfall for another, and had fallen into it himself. The meaning is, that he would bring ruin upon himself while he was plotting the rain of others; see Psalm 9:16, "The wicked is snared by the work of his own hands;" compare the note at Job 5:13. The phrase "by his own feet" here means, that he walks there himself. He is not led or driven by others, but he goes himself into the net. Wild animals are sometimes driven, but he walks along of his own accord into the net, and has no one to blame but himself.

And he walketh upon a snare - Or a pitfall. This was formerly the mode of taking wild beasts. It was done by excavating a place in the earth, and covering it over with turf, leaves, etc. supported in a slender manner; so that the lion, or elephant or tiger that should tread on it, would fall through. These methods of taking wild beasts have been practiced from the earliest times, and are practiced everywhere.

18:8 Feet - By his own designs and actions.
