Ecclesiastes 8:5-7

New International Version - UK

⁵ Whoever obeys his command will come to no harm,
    and the wise heart will know the proper time and procedure.
⁶ For there is a proper time and procedure for every matter,
    though a person may be weighed down by misery.

⁷ Since no one knows the future,
    who can tell someone else what is to come?
