Sisera gathered together all his chariots, even nine hundred chariots of iron, and all the people who were with him, from Harosheth of the Gentiles, to the river Kishon.

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.
