Boast not thyself of to-morrow; For thou knowest not what a day may bring forth.

Do not make a noise about tomorrow, for you are not certain what a day's outcome may be.

Μη καυχασαι εις την αυριον ημεραν· διοτι δεν εξευρεις τι θελει γεννησει η ημερα.

Boast not thyself of to morrow; for thou knowest not what a day may bring forth.
