Barak was a ruler of Ancient Israel. As military commander in the biblical Book of Judges, Barak, with Deborah, from the Tribe of Ephraim, the prophet and fourth Judge of pre-monarchic Israel, defeated the Canaanite armies led by Sisera.

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.
