All things have I seen in the days of my vanity, Solomon had taken note of everything possible while enjoying the empty life of this world; there is a just man that perisheth in his righteousness, his plans were failures, and he himself died in misfortune because he placed the emphasis upon a mere outward show of perfection only, and there is a wicked man that prolongeth his life in his wickedness. Cf Psalms 73:3-12.
