There is in this moment an ironic juxtaposition of victor and vanquished in the same tent of Jael…. The woman has in effect conquered them both: Sisera, by depriving him of life, and Barak, by depriving him of the honour that should have been his as the chosen deliverer. Interestingly, the true identity of the woman is delayed as long as possible so that the irony is nicely turned against the reader.
