Jael or Yael is a heroine of the Battle of Mount Tabor, described in chapters 4 and 5 of the Book of Judges. In the account, she delivers the Israelites from the army of King Jabin of the city of Hazor in Canaan. After Barak demurs at the behest of the prophetess Deborah, God turns Sisera over to Jael, who kills him by driving a tent peg through his skull after he enters her tent near the great tree in Zaanaim near Kedesh.

The Book of Judges is the seventh book of the Hebrew Bible and the Christian Old Testament. In the narrative of the Hebrew Bible, it covers the time between the conquest described in the Book of Joshua and the establishment of a kingdom in the Books of Samuel, during which Biblical judges served as temporary leaders.
