4:15 LORD discomfited Sisera. The providential means by which the hosts of Sisera, with their nine hundred iron chariots, were destroyed by Barak’s ten thousand men, is indicated in the song of Deborah and Barak (Judges 5:21): “The river of Kishon swept them away.” The chariots were inundated by the floodwaters and the remaining soldiers “fell upon the edge of the sword” (Judges 4:16).
