This seems to be an elliptical statement of a hypothetical case: "If a man dies, he will not live again, but if he did, all the days of my hard service I would wait for my release to come." (See: [[rc://en/ta/man/jit/figs-ellipsis]] and [[rc://en/ta/man/jit/figs-hypo]])
The abstract noun "release" can be expressed with the verb "release." Alternate translation: "until I should be released" or "until you release me" (See: [[rc://en/ta/man/jit/figs-abstractnouns]])
