'Sorrow' in the Bible

For in much wisdom is much grief: and he that increaseth knowledge increaseth sorrow.

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

Sorrow is better than laughter: for by the sadness of the countenance the heart is made better.

Therefore remove sorrow from thy heart, and put away evil from thy flesh: for childhood and youth are vanity.
