'Vexation' in the Bible

For in much wisdom is much vexation, and he that increaseth knowledge increaseth sorrow.

For all his days are sorrows, and his travail vexation: even in the night his heart taketh no rest. This also is vanity.

All his days also he eateth in darkness, and hath much vexation, and sickness, and irritation.

Vexation is better than laughter; for by the sadness of the countenance the heart is made better.

Be not hasty in thy spirit to be vexed; for vexation resteth in the bosom of fools.
