2 Samuel 22:43

Then did I beat them as small as the dust of the earth, I did stamp them as the mire of the street, and did spread them abroad.

Cross-reference

Psalm 18:42 is the exact parallel verse — 'I beat them fine as dust, trampled like mud' — the same song recorded elsewhere.

Psalm 18:41 is from the same victory song — here the enemies cry out unanswered, then David crushes them (v42).

Malachi 4:3 promises the righteous will trample the wicked like ashes — similar victory imagery, but eschatological.
