Psalm 37:2

For they wither quickly like grass
and wilt like tender green plants.

until I entered God’s sanctuary.
Then I understood their destiny.

You end their lives; they sleep.
They are like grass that grows in the morning—

though the wicked sprout like grass
and all evildoers flourish,
they will be eternally destroyed.

He blossoms like a flower, then withers;
he flees like a shadow and does not last.

the joy of the wicked has been brief
and the happiness of the godless has lasted only a moment?

I have seen a wicked, violent man
well-rooted like a flourishing native tree.

Let all who hate Zion
be driven back in disgrace.

but the one who is rich should boast in his humiliation because he will pass away like a flower of the field.

For

All flesh is like grass,
and all its glory like a flower of the grass.
The grass withers, and the flower falls,

For they shall soon be cut down like the grass, and wither as the green herb.
