Ecclesiastes 8:7; Ecclesiastes 8:15; Ecclesiastes 8:17

7 Because he is ignorant of things past, and things to come he cannot know by any messenger.

15 Therefore I commended mirth, because there was no good for a man under the sun, but to eat, and drink, and be merry, and that he should take nothing else with him of his labour in the days of his life, which God hath given him under the sun.

17 And I understood that man can find no reason of all those works of God that are done under the sun: and the more he shall labour to seek, so much the less shall he find: yea, though the wise man shall say, that he knoweth it, he shall not be able to find it.
