Job 20:23

“[When] he is about to fill his belly, etc.] Either in a literal sense, when he is about to take an ordinary meal to satisfy nature; or in a figurative sense, when he is seeking to increase his worldly riches, and his barns and coffers, and endeavouring to get satisfaction therein: [God] shall cast the fury of his wrath upon him; or “send it out on him” f792 ; out of the treasures of it, which are laid up with him, (<053234>Deuteronomy 32:34,35); into his conscience, and fill him with a dreadful sense and apprehension of it, and that with great force and violence, and cast it, and pour it on him like fire, or any scalding liquor, which is very terrible and intolerable. This intends the…”

“Rather, "God shall cast (may God send) [UMBREIT] upon him the fury of His wrath to fill his belly!" while . . . eating--rather, "shall rain it upon him for his food!" Fiery rain, that is, lightning (Psa 11:6; alluding to Job's misfortune, Job 1:16). The force of the image is felt by picturing to one's self the opposite nature of a refreshing rain in the desert (Exo 16:4; Psa 68:9).”

“When he is about to fill his belly - Or rather, “there shall be enough to fill his belly.” But what “kind” of food it should be, is indicated in the following part of the verse. “God” would fill him with the food of his displeasure. It is spoken sarcastically, as of a gormandizer, or a man who lived to enjoy eating, and the meaning is, that he should for once have enough. So Rosenmuller interprets it. God shall cast the fury - This is the kind of food that he shall have. God shall fill him with the tokens of his wrath - and he shall have enough. And shall rain it upon him while he is eating - Noyes renders this, “And rain it down upon him for his food.” The meaning is, that God would pour…”

“Rain - This phrase denotes both the author of his plagues, God, and the nature and quality of them, that they shall come upon him like rain; with great vehemency, so that he cannot prevent or avoid it. Eating - As it fell upon thy sons. Job 20:24”

“he is about: Num 11:33; Psa 78:30, Psa 78:31; Mal 2:2; Luk 12:17-20 rain it: Gen 19:24; Exo 9:23; Psa 11:6, Psa 78:30, Psa 78:31; Isa 21:4 Job 20:24”
