Job 38:21

Knowest thou it, because thou wast then born? -This may either be a question, or it may be spoken ironically. According to the former mode of rendering it, it is the same as asking Job whether he had lived long enough to understand where the abode of light was, or whether he had an existence when it was created, and knew where its home was appointed. According to the latter mode, it is keen sarcasm. “Thou must know all this, for thou art so old. Thou hast had an opportunity of observing all this, for thou hast lived through all these changes, and observed all the works of God.” This latter method of interpreting it is adopted by Umbreit, Herder, Noyes, Rosenmuller, and Wemyss.
