KJ2000(i)
21 For there is a man whose labor is in wisdom, and in knowledge, and in equity; yet to a man that has not labored in it shall he leave it for his portion. This also is vanity and a great evil.
22 For what has man for all his labor, and for the striving of his heart, with which he has labored under the sun?
23 For all his days are sorrows, and his travail grief; yea, his heart takes not rest in the night. This is also vanity.
