This chapter is a real turn-up for the books within such a patriarchal society as Israel. For now a woman named Deborah was the judge who ruled the land! Israel had slipped back into disobedience after Ehud, and this led to them being dominated by a Canaanite king whose name was Jabin and whose army commander was Sisera. Sisera cruelly oppressed Israel for 20 years with his 900 iron chariots. Then Israel cried to the Lord for help.
It was judge and prophetess Deborah who led Israel out of their trouble. She commanded Barak to lead 10,000 men to Mount Tabor to there defeat Sisera, but Barak said he would only go if Deborah went with him, to which she agreed. They then engaged with Sisera in battle at Mount Tabor and delivered them a crushing defeat, with Sisera fleeing for his life to the tent of Jael, the wife of Heber the Kenite. She gave Sisera milk to drink as he was thirsty and exhausted, and then he went to sleep. There Jael drove a tent peg into his head and killed him.
So it was that Israel was delivered from the Canaanite king and his mighty army. Judge Deborah led Israel into routing Sisera's army and Jael finished off Sisera who was the Canaanite army's commander in chief! The women, Deborah and Jael, were used by God to bring complete victory to Israel!
