This verse refers to a common threat in the old world. Certain religions contemporaneous with these early writings advocated having orgies that culminated with the burning of some of the participant's children. Others would use dog pits or bear pits instead of fire. Essentially the orgies were a religious observance, and the children were killed at the culmination of days of religious observances. The sights and sounds of the burning children were reported to increase the ecstatic frenzy of the participants to incredible levels.
