'Sank' in the Bible

So they took Jeremiah and dropped him into the cistern of Malchiah the king’s son, which was in the guard’s courtyard, lowering Jeremiah with ropes. There was no water in the cistern, only mud, and Jeremiah sank in the mud.

‘All the women who remain in the palace of Judah’s king will be brought out to the officials of the king of Babylon and will say:Your trusted friends misled youand overcame you.Your feet sank into the mire,and they deserted you.
