Judges 4:12-14

The Voice

¹² When Sisera the general heard that Barak, the son of Abinoam, had gone up in force to Mount Tabor, ¹³ he called out all 900 of his iron chariots, and all the soldiers who were with him from Harosheth-hagoyim to the wadi Kishon.

So Barak went down from Mount Tabor with 10,000 warriors following.
