Jael pounds a tent stake through a sleeping man's skull

In the last killing, God "discomfited" the Canaanite army, causing them all to be killed. (It's not clear how God did this, but he probably forced them to kill each other. He likes doing stuff like that.)

But Sisera, the captain of the Canaanite army, somehow managed to escape. And that night he passed by Heber's tent (Heber was an ally of the Canaanites), which is where Jael enters the story.

Jael was Heber's wife and she came out to greet Sisera, inviting him to stay the night in their tent. She prepared a bed for him, gave him a bottle of milk, and tucked him in for the night.

Jael went out to meet Sisera, and said unto him, Turn in, my lord, turn in to me; fear not. And when he had turned in unto her into the tent, she covered him with a mantle. And he said unto her, Give me, I pray thee, a little water to drink; for I am thirsty. And she opened a bottle of milk, and gave him drink, and covered him. Judges 4:18-19

Then, after he was asleep, she drove a tent stake through his head.

Then Jael Heber's wife took a nail of the tent, and took an hammer in her hand, and went softly unto him, and smote the nail into his temples, and fastened it into the ground: for he was fast asleep and weary. So he died. 4:21

OK, so what, you say. Why blame this killing on God?

Because God blamed it on himself. Deborah, who was a prophetess, said the killing would take place, and that God would take an active part.

The LORD shall sell Sisera into the hand of a woman. 4:9

After the killing Deborah even wrote a little song about Jael and her blessed hammer.

Blessed above women shall Jael the wife of Heber the Kenite be,
blessed shall she be above women.

He asked water, and she gave him milk;
she brought forth butter in a lordly dish.

She put her hand to the nail,
and her right hand to the workmen's hammer;

and with the hammer she smote Sisera, she smote off his head,
when she had pierced and stricken through his temples. 5:24-26

So there you have it. Jael is the most blessed of all women. I think there's even a well-known prayer about it.

It goes like this:

Hail Jael, full of grace. The Lord is with thee. Blessed art thou among women....

Or maybe I'm confusing it with another prayer.
