'Mud' in the Bible

So they took Jeremiah and threw him into the pit [of] Malchiah, the son of the king, which [was] in the courtyard of the guard. And they let Jeremiah down by ropes. Now in the pit there was no water, {but only} mud, and Jeremiah sank in the mud.

Now look, all the women who remain in the house of the king of Judah [are] being led out to the officials of the king of Babylon. And look, [they are] saying, '{Your trusted friends} have misled you, and they have prevailed against you. Your feet are stuck in the mud, [so] they turned backward.'
