1 Peter 1:24

“A voice says, “Cry out.” And I asked, “What shall I cry?” “All people are like grass, and all their faithfulness is like the flowers of the field. The grass withers and the flowers fall, because the breath of the Lord blows on them. Surely the people are grass. The grass withers and the flowers fall, but the word of our God endures forever.””

Similar imagery of fading flowers and enduring word.

“The life of mortals is like grass, they flourish like a flower of the field; the wind blows over it and it is gone, and its place remembers it no more.”

Uses the same 'grass' and 'flower' metaphor to describe the fleeting nature of human life.

“but the rich should boast in their humiliation—since they will pass away like a wild flower. For the sun rises with scorching heat and withers the plant; its blossom falls and its beauty is destroyed. In the same way, the rich will fade away even while they go about their business.”

Illustrates the transience of earthly things using the imagery of a fading flower.
