'Clods' in the Bible

My flesh is clothed with worms and clods of dust; My skin closeth up, and breaketh out afresh.

The clods of the valley shall be sweet unto him, And all men shall draw after him, As there were innumerable before him.

When the dust runneth into a mass, And the clods cleave fast together?

And Ephraim is a heifer that is taught, that loveth to tread out the grain ; but I have passed over upon her fair neck: I will set a rider on Ephraim; Judah shall plow, Jacob shall break his clods.

The seeds rot under their clods; the garners are laid desolate, the barns are broken down; for the grain is withered.
