Albert Barnes Commentary Psalms 88:16

"Thy fierce wrath is gone over me; Thy terrors have cut me off." — Psalms 88:16 (ASV)

Your fierce wrath goes over me – Like waters. See (Psalms 88:7).

Your terrors have cut me off – That is, I am as one already dead; I am so near to death that I may be spoken of as dead.
