'Mud' in the Bible

I'm sending my fury against a godless nation, and I'll command him against the people with whom I'm angry to seize loot and snatch plunder, and to trample them down like mud in the streets.

"You are stirring up one from the north, and they are coming from the rising of the sun; and he will be called by his name. Rulers will arrive like mud; just like a potter, he will trample the clay.

But the wicked are tossed like the sea; for it is not able to keep still, and its waters toss up mire and mud.
