Lord, Let Me Know Mine End

Lord, let me know mine end, and the number of my days: that I may be certified how long I have to live
Behold, thou hast made my days as it were a span long: and mine age is even as nothing in respect of thee; and verily every man living is altogether vanity
For man walketh in a vain shadow, and disquieteth himself in vain: he heapeth up riches, and cannot tell who shall gather them
And now, Lord, what is my hope: truly my hope is even in thee
I became dumb, and opened not my mouth: for it was thy doing
Take thy plague away from me: I am even consumed by the means of thy heavy hand
When thou with rebukes dost chasten man for sin, thou makest his beauty to consume away, like as it were a moth fretting a garment: every man therefore is but vanity
