The correct answer is C. Jael. Detailed Explanation:

1. Context of the Story: The story of Sisera's death is found in the Book of Judges, specifically in Judges 4 and 5. Sisera was the commander of the army of King Jabin of Canaan, who oppressed the Israelites for twenty years. The Israelites cried out to God for help, and God raised up Deborah, a prophetess and judge, to lead them.
2. Deborah and Barak's Role: Deborah summoned Barak, a military leader, and instructed him to gather an army to fight against Sisera. Barak, however, was hesitant and insisted that Deborah accompany him into battle. Deborah agreed but prophesied that the glory of victory would not go to Barak but to a woman.
3. The Battle: In the ensuing battle, God caused confusion among Sisera's troops, leading to their defeat. Sisera fled the battlefield and sought refuge in the tent of Jael, the wife of Heber the Kenite, who was allied with Jabin.
4. Jael's Act: While Sisera was resting in her tent, Jael offered him hospitality, giving him milk to drink and covering him with a blanket. When he fell asleep, Jael took a tent peg and a hammer and drove the peg through Sisera's temple, killing him. This act fulfilled Deborah's prophecy that a woman would receive the glory for Sisera's defeat.
5. Significance of Jael's Action: Jael's actions are significant in the narrative as they highlight themes of courage, the unexpected roles women can play in biblical history, and God's sovereignty in delivering Israel from oppression. Jael is often celebrated for her decisive action, which led to the complete defeat of Sisera and the liberation of the Israelites.

Why the Other Options Are Incorrect:

• A. Deborah: While Deborah played a crucial role in leading the Israelites and prophesying Sisera's defeat, she did not kill him. Her leadership and encouragement were vital, but the actual act of killing Sisera was performed by Jael.
• B. Barak: Barak was the military leader who fought against Sisera's army, but he did not kill Sisera. His role was to lead the Israelite forces into battle, and he was present during the conflict, but he did not confront Sisera directly.
• D. Joshua: Joshua was a prominent leader of the Israelites who succeeded Moses and led them into the Promised Land. However, he lived before the time of Deborah and Sisera. Therefore, he had no involvement in this particular story.

Revision Summary:

• Sisera was killed by Jael, who drove a tent peg through his head while he was asleep in her tent.
• Deborah was a prophetess and judge who led the Israelites and prophesied Sisera's defeat but did not kill him.
• Barak was the military leader who fought Sisera's army but did not confront or kill Sisera directly.
• Joshua was a leader before Deborah's time and had no role in the events surrounding Sisera's death.

This understanding of the story emphasizes the importance of Jael's actions and the broader themes of God's deliverance and the roles of women in biblical narratives.
