Job 30:8

“[They were] children of fools, etc.] Their parents were fools, or they themselves were such; foolish children, or foolish men, were they that derided Job; and their derision of him was a proof of it: the meaning is not that they were idiots, or quite destitute of reason and natural knowledge, but that they were men of slender capacities; they were “Nabal like”, which is the word here used of them; and, indeed, it may easily be concluded, they could not have much knowledge of men and things, from their pedigree, education, and manner of living before described; though rather this may signify their being wicked men, or children of such, which is the sense of the word “fool” frequently in the…”

“fools--that is, the impious and abandoned (Sa1 25:25). base--nameless, low-born rabble. viler than, &c.--rather, they were driven or beaten out of the land. The Horites in Mount Seir (Gen 14:6 with which compare Gen 36:20-21; Deu 2:12, Deu 2:22) were probably the aborigines, driven out by the tribe to which Job's ancestors belonged; their name means troglodytÃ&brvbr, or "dwellers in caves." To these Job alludes here (Job 30:1-8, and Gen 24:4-8, which compare together).”

“They were children of fools - The word rendered “fools” נבל nâbâl, means, (1) stupid, foolish; and (2) abandoned, impious; compare 1 Samuel 25:3, 1 Samuel 25:25. Here it means the worthless, the refuse of society, the abandoned. They had no respectable parentage. Umbreit, “A brood of infamy.” Coverdale, “Children of fools and villains.” Children of base men - Margin, as in Hebrew, “men of no name.” They were men of no reputation; whose ancestors had in no way been distinguished; possibly meaning, also, that they herded together as beasts without even a name. They were viler than the earth - Gesenius renders this, “They are frightened out of the land.” The Hebrew word (כאה) means “to chide,…”
