Sirach 3:25

25 Without eyes thou shalt want light: profess not the knowledge therefore that thou hast not.

Sirach 3:25 In-Context

23 Be not curious in unnecessary matters: for more things are shewed unto thee than men understand.

24 For many are deceived by their own vain opinion; and an evil suspicion hath overthrown their judgment.

25 Without eyes thou shalt want light: profess not the knowledge therefore that thou hast not.

26 A stubborn heart shall fare evil at the last; and he that loveth danger shall perish therein.

27 An obstinate heart shall be laden with sorrows; and the wicked man shall heap sin upon sin.
