So I perceived there is nothing better than for people to enjoy their work, because that is their reward; for who can show them what the future holds?

For no one knows what is best for a person during his life -- during the few days of his fleeting life -- for they pass away like a shadow. Nor can anyone tell him what the future will hold for him on earth.

In times of prosperity be joyful, but in times of adversity consider this: God has made one as well as the other, so that no one can discover what the future holds.

It is best to take hold of one warning without letting go of the other warning; for the one who fears God will follow both warnings.
