'Sorrow' in the Bible

For with much wisdom there is much sorrow; the more someone adds to knowledge, the more someone adds to grief.

Indeed, all of his days are filled with sorrow, and his struggles bring grief. In fact, his mind remains restless throughout the night. This is pointless, too!

Furthermore, all his days he lives in darkness with great sorrow, anger, and affliction.

Sorrow is better than laughter, because the heart is made better through trouble.

Banish sorrow from your heart, and evil from your body, since both childhood and the prime of life are pointless.
