The narrative is based on the Biblical legend of a hero named Jephthah. In order to gain God's support, the military leader swore to sacrifice to Him the person who would be the first to congratulate him on his victory. Jephthah's only and beloved daughter was the first. The father fulfilled the vow to God. Unlike the ancient tale, the main character of the narrative is not the commander, but his daughter Avital. Intelligent and sophisticated Avital burned in the fire of the harsh tenets of the faith. The story is a free interpretation of the Biblical legend. The author introduced characters required by the plot - bearers of ideas and passions.
