Job 19:29

“Be ye afraid of the sword, etc.] Not of the civil magistrate, nor of a foreign enemy, but of the avenging sword of divine justice; lest God should whet the glittering sword of his justice, and his hand should take hold of judgment, in order to avenge the wrongs of the innocent; unless the other should also be considered as his instruments: for wrath [bringeth] the punishments of the sword, or “sins of the sword” f765 : the sense is, either that the wrath of men, in persecuting the people of God, puts them upon the commission of such sins as deserve to be punished with the sword, either of the civil magistrate, or of a foreign enemy, or of divine justice; or else the wrath of God brings on…”

“wrath--the passionate violence with which the friends persecuted Job. bringeth, &c.--literally, "is sin of the of the sword" that ye may know--Supply, "I say this." judgment--inseparably connected with the coming of the Vindicator. The "wrath" of God at His appearing for the temporal vindication of Job against the friends (Job 42:7) is a pledge of the eternal wrath at the final coming to glorify the saints and judge their enemies (Th2 1:6-10; Isa 25:8). Next: Job Chapter 20”

“Be ye afraid of the sword - Of the sword of justice, of the wrath of God. In taking such views, and using such language, you ought to dread the vengeance of God, for he will punish the guilty. For wrath bringeth the punishments of the sword - The word “bringeth” is supplied by the translators, and as it seems to me improperly. The idea is, that wrath or anger such as they had manifested, was proper for punishment; that such malice as they had shown was a crime that God would not suffer to escape unpunished. They had, therefore, everything to dread. Literally, it is, “for wrath the iniquities of the sword;” that is, wrath is a crime for the sword. That ye may know that there is a judgment -…”

“Sword - Of some considerable judgment to be inflicted on you which is called the sword, as Deu 32:41, and elsewhere. That - This admonition I give you, that you may know it in time, and prevent it. A judgment - God sees and observes, and will judge all your words and actions. Next: Job Chapter 20”

“19:29 Given the biblical principles against bearing false witness (13:7-11; see Matt 7:1-2; Jas 4:11-12), Job warned his friends that they should fear God’s judgment. They did eventually face his judgment, but they also received mercy (Job 42:7-8).”
