'Complete' in the Bible

Then I examined all of my accomplishments that I had brought about by my own efforts, including the work that I had labored so hard to complete and it was all pointless, like chasing after the wind, and there was nothing to be gained on earth.

When thou vowest a vow to God, delay not to complete it, for there is no pleasure in fools; that which thou vowest -- complete.

Better that thou do not vow, than that thou dost vow and dost not complete.
