And Zagnugael, the angel of the Lord, appeared to him in a flame of fire in the midst of the bush. And he gazed, and, behold, the bush burned with fire, yet the bush was neither burned nor consumed with fire.
Targum Jerusalem
And he looked, and, behold, the bush burned with fire, yet remained in freshness, (or, was moist), neither was it consumed.
