Who was Sisera's mother?

       Sisera's mother (Judg. 5:28) represents the aged mother, watching longingly for her warrior son to return from battle. Sisera, a Canaanite chieftain of the twelfth century B.C., had already been killed by Jael, the Kenite wife, who had driven a tent peg into his head while, wearied from battle, he lay sleeping.
       After many of his men had perished in the floodwaters of the Kishon, Sisera had sought refuge in the tent of Jael and her husband Heber, the Kenite, thinking of course they were friendly to his cause (Judges. 4:17).
       Sisera's mother, we know, was a luxury-loving, materially minded woman. She does not appeal to God for her son's safe return. On the other hand, we see her sitting beside the latticed windows of her palace, and she is asking, "Why is his chariot so long in coming?" Her ladies-in-waiting comfort her by stories of the wild spoils of war. They tell her that her son, Sisera, is late because, like all sons of war, he has probably received a damsel or two. Also they picture to her the rich garments that her son will bring back, garments luxuriant in their colors and rich in their embroideries.
       The story of Sisera's mother appears in Deborah's Song.
