Job 21:30 - Matthew Poole's English Annotations on the Holy Bible

That the wicked, & c. this is the thing which they might learn of passengers. Reserved; or, withheld, or kept back, to wit, from falling into common calamities, though in truth he be not so much kept from evil as kept for evil; he is reserved from a less, that he may be swallowed up in a greater misery; as Pharaoh was kept from the other plagues, that he might be drowned in the sea. They shall be brought: he speaketh of the same person; only the singular number is changed into the plural, possibly to intimate, that although for the present only some wicked men were punished, yet then all of them should suffer. Shall be brought forth, to wit, by the conduct of God's providence and justice, as malefactors are brought forth from prison to judgment and execution, though they be brought to it slowly, and by degrees, and with some kind of pomp and state, as this word signifies. To the day of wrath; Heb. to the day of wraths, i.e. of special and extraordinary wrath; either to some terrible and desolating judgments, which God sometimes sends upon wicked princes or people; or to the day of the last and general judgment, which is called in Scripture the day of wrath; for the day of the general resurrection and judgment was not unknown to Job and his friends, as appears from Job 19:25, &c, and other passages of this book.
