Charles Ellicott Commentary Judges 5:22

"Then did the horsehoofs stamp By reason of the prancings, the prancings of their strong ones." — Judges 5:22 (ASV)

By the means of the pransings. —Rather, the stampings. In crossing the Kishon after moderate rains, I had an opportunity to observe from personal experience how easily a horse could be hopelessly disabled in the muddy morass formed by the river. The word is forcibly repeated by the figure known as anadiplosis.

Their mighty ones. —The great lords in their iron chariots, trying to goad their frightened horses through the flood. There is a scathing taunt in the words. Their "might" was exhibited in valiantly running away. It may, however, mean the strong horses themselves (Jeremiah 51:11). Vandevelde speaks of the Kishon as being the most dangerous river of the land, from its quicksands.
