Yahweh confused Sisera, and all his chariots, and all his host, with the edge of the sword before Barak; and Sisera alighted from his chariot, and fled away on his feet.
Now, Moses' father-in-law, his family sort of came with the children of Israel but here this guy's sort of a trader. He was a nark, actually informed on the fact that Sisera was there in Mount Tabor with his army. He let them know. And so Sisera came down with his army, the nine hundred chariots and the whole thing.
