Boast not thyself of tomorrow; For thou knowest not what a day may bring forth.
Wherefore I saw that there is nothing better, than that a man should rejoice in his works; for that is his portion: for who shall bring him (back) to see what shall be after him?
For who knoweth what is good for man in (his) life, all the days of his vain life which he spendeth as a shadow? for who can tell a man what shall be after him under the sun?
