Man's days are like grass
Human life is short. The life of man passes quickly and is fleeting. Also: Man is weak against his fate.
("As for man, his days are like grass; as a flower of the field, so he flourishes. For the wind passes over it, and it is gone; and its place knows it no more. But the mercy of the Lord is from everlasting to everlasting upon them that fear him, and his righteousness unto children's children" - Psalms 103:15, and also: "Man's days are like grass./ His days are like grass./ The days of man are like grass/ his days./ Do not fear" - Nathan Zach/ Man's days are like grass)
