Albert Barnes Commentary Psalms 69:1

"Save me, O God; For the waters are come in unto my soul." — Psalms 69:1 (ASV)

Save me, O God - That is, interpose and deliver me from the dangers which have come upon me.

For the waters are come in unto my soul - So as to endanger my life. Waters, deep, raging, overwhelming, are images of calamity or danger. See the notes at Psalms 32:6. Compare Psalms 42:7.
