"Man that is born of woman is of few days, and full of trouble. He springs up like a flower and withers away; like a shadow he flees and does not continue. You have appointed his days from birth to death" (Job 14:1-5)
Over time, the phrase "from cradle to the grave" has taken on a more general meaning, referring to the entire course of a person's life, including all of the experiences, challenges, and joys that come with it. It is often used in a reflective way, to ponder the brevity and significance of human existence.
