Job 18:20

In his days the last shall be astonied, and horror shall seize on the first.

For he will then let himself loose against the righteous with such a measure of iniquity, that even the hearts of the very Elect shall be struck with no small consternation. Whence it is written, Insomuch that if it were possible, they shall deceive the very Elect. Which, clearly, is said, not because the Elect shall fall, but because they shall tremble with terrible alarms. Now at that time both the latest Elect and the first Elect are described as maintaining the conflict for righteousness against him, in that both they that shall be found among the Elect at the end of the world, are destined to be laid low in the death of the flesh, and they too who proceeded from the former divisions of the world, i.e. Enoch and Elijah, shall be brought back amongst men, and shall be exposed to the savageness of his cruelty still in their mortal flesh. This one's forces let loose in such terrible power, 'the latest are astonied at, and the first do dread,' in that, though in respect of this, viz. that he is lifted up by a spirit of pride, they despise all his temporal power, yet in respect of this, that they are themselves still in mortal flesh, wherein they are liable to suffer temporal anguish, they dread the very punishments, which they bear with resolution; so that there is in them at one and the same time both constancy derived from virtue, and alarm proceeding from the flesh; in that though they be of the number of the Elect, so that they cannot be overcome by torments, yet from this only that they are men, they fear the very torments, that they overcome. So let it be said, In his days the last shall be astonied, and terror shall seize on the first. In that he shall then shew forth such signs, and do things so cruel and hard hearted, as to force them to astonishment, whom he shall find at the end of the world, and to pierce with the pang of carnal death the first fathers, who are reserved for his extirpation. Therefore whereas he has described many particulars relating to all the wicked, or to the head of the wicked himself, he immediately adds with a general description.

He shows the effect that follows from this in the hearts of others when he then says, "On his day," which is the day of his ruin, "the youngest men will be astonished," i.e. the youngest members of the people will be stunned with great wonder, not able comprehend how such great glory of a sinner has suddenly been reduced to nothing. As for the elders he then says, "horror will invade the first men," fearing that the same thing might happen to them. He seems to have introduced this to answer to what Job had said above, "Whether his sons are noble or base, he will not understand, yet his flesh, while he lives, will grieve." (14:21) From this Job seemed to have refuted the threats of his friends or their promises of things which would happen after his death. But here Baldath answers that great tragedies of this kind which happen after death, although the dead man does not know about them, are still inflicted by God—with such punishments—for the correction of others.
