Jeremiah 38:6

38:6 So the officials took Jeremiah and put him in the cistern of Malkijah, one of the royal princes, that was in the courtyard of the guardhouse. There was no water in the cistern, only mud. So when they lowered Jeremiah into the cistern with ropes he sank in the mud.

Psalms 69:2

69:2 I sink into the deep mire

where there is no solid ground;

I am in deep water,

and the current overpowers me.

Psalms 69:14

69:14 Rescue me from the mud! Don’t let me sink!

Deliver me from those who hate me,

from the deep water!
