Ecclesiastes 3:20-22 New English Translation (NET Bible)
20 Both go to the same place,
both come from the dust,
and to dust both return.
21 Who really knows if the human spirit ascends upward,
and the animal’s spirit descends into the earth?
22 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?
