I searched in my heart how to cheer my flesh with wine, my heart yet guiding me with wisdom, and how to lay hold on folly, till I might see what it was good for the sons of men that they should do under heaven all the days of their life.

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 good that thou shouldest take hold of this; yea, also from that withdraw not thy hand: for he that feareth God shall come forth from them all.

For even man knoweth not his time; as fish that are taken hold of by an evil net, and as birds that are taken hold of by a snare, like these are the sons of man snared at an evil time, when it falleth upon them suddenly.
