David
Psalm 37:20BSB·traditional attribution

But the wicked and enemies of the LORD will perish like the glory of the fields. They will vanish; like smoke they will fade away.

John Calvin Reformed @genevareformer

PSALM 37 This psalm, the title of which shows it to have been composed by David, contains most profitable instruction. Since the faithful, so long as they pursue their earthly pilgrimage through life, see things strangely confused in the world, unless they assuaged their grief with the hope of a better issue, their courage would soon fail them.

C.H. Spurgeon Reformed Baptist @princeofpreachers

But the wicked shall perish. Whatever phantom light may mock their present, their future is black with dark, substantial night. Judgment has been given against them, they are but reserved for execution. Let them flaunt their scarlet and fine linen, and fare sumptuously every day; the sword of Damocles is above their heads, and if their wits were a little more awake, their mirth would turn to misery.
