'Fleeting' in the Bible

Like a dream upon awakening, when [you] wake up, O Lord, you will despise their fleeting form.

He who makes treasure by a lying tongue [is a] fleeting vapor [and] seeker of death.

For the fate of {humans} and the fate of the beast is {the same}. The death of the one is like the death of the other, for {both are mortal}. Man has no advantage over the beast, for both are fleeting.

For who knows what [is] good for a man in his life during the few days of his fleeting life, which are fleeting as a shadow? For who can tell anyone what will happen {in the future} under the sun?
