LITV(i)
21 When there is a man whose labor is with wisdom, and with knowledge, and with advantage; yet he shall give it to a man who has not labored with it, for his share; this also is vanity and a great evil.
22 For what is there for man in all his labor, and in longing of his heart, which he has labored under the sun?
23 For all his days are pains, and his task is grief; his heart does not even take rest in the night. Even this also is vanity.
