for, in abundance of wisdom is abundance of sadness, and he who addeth knowledge addeth pain.'

For all day long his work produces pain and frustration, and even at night his mind cannot relax! This also is futile!

All his days are in the dark, and he has much sorrow, pain, disease, and trouble.

He removing stones; shall suffer pain by them; and he cleaving woods asunder shall be endangered by them.

Remove sorrow from your heart,
and put away pain from your flesh,
because youth and the prime of life are fleeting.
