'Frailty' in the Bible

Remember how fleeting my lifetime is;For what vanity, [for what emptiness, for what futility, for what wisp of smoke] You have created all the sons of men!

For the creation was subjected to frustration and futility, not willingly [because of some intentional fault on its part], but by the will of Him who subjected it, in hope

extinguished the power of [raging] fire, escaped the edge of the sword, out of weakness were made strong, became mighty and unbeatable in battle, putting enemy forces to flight.

and the rich man is to glory in being humbled [by trials revealing human frailty, knowing true riches are found in the grace of God], for like the flower of the grass he will pass away.
