'Sink' in the Bible

I sink in deep mire, where there is no standing: I am come into deep waters, where the floods overflow me.

Deliver me out of the mire, and let me not sink: let me be delivered from them that hate me, and out of the deep waters.

And thou shalt say, Thus shall Babylon sink, and shall not rise from the evil that I will bring upon her: and they shall be weary. Thus far are the words of Jeremiah.
