'Cannot' in the Bible
What is twisted cannot be straightened, and what is lacking cannot be counted.
All his days [are] painful, his labor [brings] grief, and his heart cannot rest at night. This also [is] vanity!
Whatever is--it was already determined, {what will be--it has already been decided}. As for man, he cannot argue against what is more powerful than him.
In the day of prosperity, rejoice! But in the day of adversity, consider! For God made one in place of another so that mortals cannot find out what will happen {in the future}.
Then I saw all the work of God--man [is] not able to discover the work that is done under the sun. Although man may toil in seeking, he cannot find it. Even if a wise man claims [that he] knows it, he cannot find it.
The fool is so worn out by a hard day's work {he cannot even find his way home at night}.
