“you who ride on white female donkeys.” This refers to the wealthy. The poorer people walked on the road, as Judges 5:10 says. The color could be “white” or simply “light-colored” (NET).
“rich carpets.” The Hebrew word is used only here, and is related to the word “measure,” and carpet material was measured and sold even as carpet is sold by its measurements today.
“you who walk on the road.” After Deborah and Barak defeated the Canaanites, the roads were once again occupied.
