'Clods' in the Bible

My body is clothed [with] maggots and clods of dust; my skin hardens, then it gives way [again].

[The] clods of [the] valley are sweet to him; everyone will follow after him, and {before} him {they are innumerable}.

at [the] flowing of [the] dust into a cast and [the] clods cling together?

The seeds shrivel under their clods; the storehouses are desolate. The grain storage places are destroyed because grain has dried out.
