Midrash Tehillim, a collection of homiletic interpretations of the Book of Psalms, uses just that image to illuminate the fate of the wicked. In Midrash Tehillim 68, we find a powerful comparison: "As smoke is driven away, so You drive them away; as wax melts before fire, the wicked shall perish before God."

King David, in his dialogue with the Almighty, according to the Midrash, emphasizes the insubstantial nature of the wicked. They are not like smoke with substance, but rather like smoke that is easily scattered, blown away by the slightest breeze. It's a striking image, isn't it?

The Midrash offers another compelling interpretation, a parable that helps bring the concept home. Imagine a king in his upper palace, far removed from the daily grind. Below, in the lower palace, servants kindle a fire, and the smoke rises, reaching the king. In this allegory, the wicked are likened to that smoke rising from below – a nuisance, perhaps, but ultimately insubstantial and easily dismissed by the Divine King.

The prophet Isaiah echoes this sentiment. He says that those who provoke God might as well be dead. According to Isaiah, their bodies will rot away, and they will become like ashes – nothing more than remnants, easily forgotten. This echoes the Psalmist, who says, "For the wicked will perish, and the enemies of the Lord will be like the glory of the pastures; they vanish—like smoke they vanish away."

So, what happens when the smoke clears? What remains? The Midrash provides a comforting answer: "The wicked will be destroyed, and the righteous will rejoice, as it says, 'The righteous shall rejoice and be glad before God; they shall also be merry and joyful.'"

The image of smoke is a powerful reminder of the transient nature of wickedness. The wicked, like smoke, may seem present, even imposing, but ultimately lack substance and are destined to disappear. But what about us? Are we choosing to live lives of substance, lives that will leave a lasting, positive mark on the world, or are we merely contributing to the smoke? Perhaps reflecting on the image of the vanishing smoke can help us strive for a more meaningful existence, an existence rooted in righteousness and joy.
