A.T. Robertson Commentary 2 Corinthians 1:10

"who delivered us out of so great a death, and will deliver: on whom we have set our hope that he will also still deliver us;" — 2 Corinthians 1:10 (ASV)

Out of so great a death (εκ τηλικουτου θανατου). He had considered himself as good as dead.

Delivered (ερυσατο)

--will deliver (ρυσετα). Old verb ρυω, middle, ρυομα, draw oneself, as out of a pit, rescue. So Paul faces death without fear.

On whom we have set our hope (εις ον ηλπικαμεν). Perfect active indicative of ελπιζω. We still have that hope, emphasized by ετ ρυσετα (he will still deliver).
