“Sackcloth translates Hebrew saq (cf. Akkadian saqqu), dark fabric woven of thread spun from goat hair or camel hair. Haircloth was used for coarse items—tents, rugs, and sacks (Gen. 42:25; 2 Sam. 21:10; Isa. 58:5). Unrefined and inexpensive, its use as clothing denoted abasement or abjection (2 Ne. 13:24 // Isa. 3:24; Jer. 6:26; 48:37). Even the color of sackcloth bespoke deprivation (parallel with blackness in the dearth context of 2 Ne. 7:3 // Isa. 50:3)” (Largey, Book of Mormon Reference Companion, 692).
