Clod
In Job 7:5 (gish, gush, "a mass of earth"), "clods of dust," the crust of his sores, formed by the dry, swollen skin--a symptom of leprosy, though not peculiar to it. In Job 21:33; 38:38 (reghebh, "a soft clod," "lump of clay"), "The clods of the valley shall be sweet unto him," "The clods cleave fast together." In Joe 1:17 (meghraphah, "a furrow," "something thrown off" (by the spade)), "The seeds rot (m "shrivel") under their clods."
Figurative: "Jacob shall break his clods" (Ho 10:11), i.e. "must harrow for himself," used figuratively of spiritual discipline (compare Isa 28:24 the King James Version).
