Judges 4:16-20

But Barak pursued the chariots and the army as far as Harosheth-hagoyim, and all the army of Sisera fell by the edge of the sword; not even one was left.

Now Sisera fled on foot to the tent of Jael the wife of Heber the Kenite, because there was peace between Jabin the king of Hazor and the house of Heber the Kenite.

And Jael went out to meet Sisera, and said to him, “Turn aside, my master, turn aside to me! Do not be afraid.” So he turned aside to her into the tent, and she covered him with a rug.

And he said to her, “Please give me a little water to drink, for I am thirsty.” So she opened a leather bottle of milk and gave him a drink; then she covered him.

And he said to her, “Stand in the doorway of the tent, and it shall be if anyone comes and inquires of you, and says, ‘Is there anyone here?’ that you shall say, ‘No.’ ”
