But the wicked will perish: Though the LORD's enemies are like the flowers of the field, they will be consumed, they will go up in smoke.
NIV
But the wicked shall perish, and the enemies of the Lord shall be as the fat of lambs [that is consumed in smoke] and as the glory of the pastures. They shall vanish; like smoke shall they consume away.
AMP
But the wicked shall perish, and the enemies of the LORD shall be as the fat of lambs: they shall consume; into smoke shall they consume away.
