Adam Clarke on Psalms 69:1

The waters are come in unto my soul - I am in the deepest distress. The waters have broken their dikes, and are just ready to sweep me away! Save me, Lord! In such circumstances I can have no other help.

In the first, second, third, fourteenth, and fifteenth verses, the psalmist, speaking in the person of the captives in Babylon, compares their captivity to an abyss of waters, breaking all bounds, and ready to swallow them up; to a deep mire, in which there was no solid bottom, and no standing; and to a pot. in which they were about to be inclosed for ever. This is strongly figurative, and very expressive.
