Parallel
Psalms 68:3
Brenton's English Septuagint · Berean Standard Bible
I am stuck fast in deep mire, and there is no standing: I am come in to the depths of the sea, and a storm has overwhelmed me.
69:2
I have sunk into the miry depths, where there is no footing; I have drifted into deep waters, where the flood engulfs me.
