The female judge of Israel who commanded Barak to fight Sisera was Deborah.
Deborah is described in the Book of Judges as a prophetess and judge who settled disputes beneath a palm tree in the hill country of Ephraim. Israel was being oppressed by Jabin, king of Canaan, whose military commander was Sisera.
Deborah summoned Barak and told him to gather troops from Naphtali and Zebulun and lead them to Mount Tabor. Barak agreed only if Deborah accompanied him, and she warned that the ultimate honor of victory would go to a woman. The Israelite forces defeated Sisera’s army, and Sisera fled on foot.
The fleeing commander sought refuge in the tent of Jael, who gave him milk and killed him with a tent peg while he slept. Deborah and Barak then appear together in Judges 5, the poetic Song of Deborah. The common mix-up is to identify Barak as the judge or Jael as the military leader; Barak commanded the troops, Jael killed Sisera, but Deborah was the judge and prophetess who directed the campaign.
