Ecclesiastes 12:1; Ecclesiastes 12:8; Ecclesiastes 12:13-14

8 "Absolute futility," says the Teacher. "Everything is futile."
13 When all has been heard, the conclusion of the matter is: fear God and keep His commands, because this [is for] all humanity. 14 For God will bring every act to judgment, including every hidden thing, whether good or evil.
