Ecclesiastes 6:12

6:12 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.

Job 7:6-7

7:6 My days are swifter than a weaver’s shuttle

and they come to an end without hope.

7:7 Remember that my life is but a breath,

that my eyes will never again see happiness.

14:2 He grows up like a flower and then withers away;

he flees like a shadow, and does not remain.

Psalms 39:5

39:5 Look, you make my days short-lived,

and my life span is nothing from your perspective.

Surely all people, even those who seem secure, are nothing but vapor.

Psalms 144:4

144:4 People are like a vapor,

their days like a shadow that disappears.

James 4:14

4:14 You do not know about tomorrow. What is your life like? For you are a puff of smoke that appears for a short time and then vanishes.
