Deborah said to Barak, Up; for this is the day in which Yahweh has delivered Sisera into your hand; hasn't Yahweh gone out before you? So Barak went down from Mount Tabor, and ten thousand men after him.
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.
