Ecclesiastes 6:12
King James Version (1769 Blayney revision, with Apocrypha) · Berean Standard Bible
For who knoweth what is good for man in this life, all the days of his vain life (note: Heb. the number of the days of the life of his vanity) which he spendeth as a shadow? for who can tell a man what shall be after him under the sun?
For who knows what is good for a man during the few days in which he passes through his fleeting life like a shadow? Who can tell a man what will come after him under the sun?
