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

1 Remember also your Creator in the days of your youth, before the evil days come, and the years draw nigh, when you will say, "I have no pleasure in them";
8 Vanity of vanities, says the Preacher; all is vanity.
13 The end of the matter; all has been heard. Fear God, and keep his commandments; for this is the whole duty of man. 14 For God will bring every deed into judgment, with every secret thing, whether good or evil.
