However Sisera fled away on his feet to the tent of Jael the wife of Heber the Kenite; for there was peace between Jabin the king of Hazor and the house of Heber the Kenite.
Speaking of the morality of this action on Jael's part, what can be said?  The falsehood, treachery, deception and cold-blooded murder appearing in this event can only be denounced as sinful, and yet there were surely mitigating circumstances.  We can admire Jael's courage, her love of the people of God, and her audacious action in taking the life of their chief enemy.  It is nowhere indicated in the Bible that God approved of Jael's behavior in this episode.  The prophecy that something like this would surely happen cannot be interpreted as God's approval of how it happened.  Still, in the next chapter, Deborah referred to Jael as "blessed"; and Jael herself appeared to be quite happy with her achievement as she showed Sisera's body to Barak.
