'Backward' in the Bible

May Dan be a snake beside the road, a viper by the path, that bites the heels of the horse so that its rider falls backward.

When he mentioned the ark of God, Eli fell backward from his chair beside the gate. He broke his neck and died, for he was old and heavy. He had judged Israel for forty years.

The living beings moved backward and forward as quickly as flashes of lightning.
