Fat—(Heb. heleb) denotes the richest part of the animal, or the fattest of the flock, in the account of Abel's sacrifice (Gen. 4:4). It sometimes denotes the best of any production (Gen. 45:18; Num. 18:12; Ps. 81:16;147:47). The fat of sacrifices was to be burned (Lev. 3:9-11;4:8;7:3;8:25; Num. 18:17. Comp. Ex. 29:13-22; Lev. 3:3-5).
It is used figuratively for a dull, stupid state of mind (Ps 17:10).
In Joel 2:24 the word is equivalent to "vat," a vessel. The hebrew word here thus rendered is elsewhere rendered "wine-fat" and "press-fat" (Hag. 2:16; Isa. 63:2).
