LORD, make me to know mine end, and the measure of my days, what it [is; that] I may know how frail I [am].
Ver. 4. Lord, make me to know mine end] This Austin expoundeth of heaven, the end of all his troubles, which he now sighed after. But Vatablus, Calvin, and most modern interpreters conceive that David doth here ingenuously confess that he grudged against God; considering the greatness of his grief and the shortness of his life.
And the measure of my days] An ad malorum quae perfero compensationem sufficiant, whether they are likely to be enough to make me amends for nay grievous sufferings. This he seemeth to speak either out of impatience, or curiosity, at least.
That I may know how frail I am] How soon ceasing and short lived. Quam durabilis sum (Trem.). Vatablus hath it, quam mundanus sim, how long I am like to be a man of this world, this vale of misery and valley of tears.
