10. What [is] that which hath been? already is its name called, and it is known that it [is] man, and he is not able to contend with him who is stronger than he.
11. For there are many things multiplying vanity; what advantage [is] to man?
12. For who knoweth what [is] good for a man in life, the number of the days of the life of his vanity, and he maketh them as a shadow? for who declareth to man what is after him under the sun?
