Ecclesiastes
King James Version (KJV)

“Whatsoever thy hand findeth to do, do it with thy might; for there is no work, nor device, nor knowledge, nor wisdom, in the grave, whither thou goest.”
King James Version (KJV)
9:10 Whatsoever - Whatever thou hast opportunity and ability to do, do it with unwearied diligence, and vigour and expedition. For - Thou canst neither design nor act any thing there tending to thy own comfort or advantage.
