Job 4:9,10 - Joseph Benson’s Commentary on the Old and New Testaments

By the blast of God they perish, &c. These two verses are thus interpreted by Heath: By the breath of God they perish; for, at the blast of his anger, the roarings of the lion, and the growling of the black lion, are hushed, and the teeth of the young lions are broken; that is, by the mere breath of God's displeasure, or by a secret, and often undiscerned, but mighty and irresistible calamity, their projects are blasted, and they are suddenly carried away, as chaff by the wind, and come to a fearful end. Nor can they escape, were they even as strong as lions, yea, as the strongest and fiercest of them. For when the divine wrath is once kindled against them, their power is immediately broken, and in a moment they are cut off, and totally consumed. He speaks of powerful tyrants, fitly compared to lions, Ezekiel 32:2; Ezekiel 38:13; 2 Timothy 4:17, who, though for a time they persecute and oppress other men, yet in due time they are restrained and crushed by the mighty power of God. Possibly, he might intend secretly to accuse Job, or his children, that, being persons of great wealth and power, they had abused it to ruin their neighbours, and therefore were justly cut off.
