Psalms 62:9

62:9 Men are nothing but a mere breath;

human beings are unreliable.

When they are weighed in the scales,

all of them together are lighter than air.

Psalms 78:33

78:33 So he caused them to die unsatisfied

and filled with terror.

Psalms 144:4

144:4 People are like a vapor,

their days like a shadow that disappears.

Ecclesiastes 6:11-12

6:11 The more one argues with words, the less he accomplishes.

How does that benefit him?

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.
