Charles Ellicott Commentary Job 11:17

"And [thy] life shall be clearer than the noonday; Though there be darkness, it shall be as the morning." — Job 11:17 (ASV)

Thine age shall be clearer than the noonday. —Rather, there will arise for you a lifetime brighter than the noonday; you will soar on high; you will be like the morning, which is conceived of as having wings (Psalms 139:9). (Compare to Malachi 4:2, of the Sun of Righteousness.) This is how we understand the word rendered thou shalt shine forth. Many take it as a substantive, meaning darkness, in which case we must render, even if there is darkness, you will be as the morning.
