Ecclesiastes 2:14; Ecclesiastes 5:17; Ecclesiastes 6:4; Ecclesiastes 11:8

14 The wise man's eyes are in his head; but the fool walketh in darkness: and I myself perceived also that one event happeneth to them all.

17 All his days also he eateth in darkness, and he hath much sorrow and wrath with his sickness.

4 For he cometh in with vanity, and departeth in darkness, and his name shall be covered with darkness.

8 But if a man live many years, and rejoice in them all; yet let him remember the days of darkness; for they shall be many. All that cometh is vanity.
