Ecclesiasticus 3

21Seek not out things that are too hard for thee, neither search the things that are above thy strength.

22But what is commanded thee, think thereupon with reverence, for it is not needful for thee to see with thine eyes the things that are in secret.

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

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