Exo 3:4 | JFB | STEP | 4. when the Lord saw that he turned aside to see-- The manifestations which God anciently made of Himself were always accompanied by clear, unmistakable signs that the communications were really from heaven. This certain evidence was given to Moses. He saw a fire, but no human agent to kindle it; he heard a voice, but no human lips from which it came; he saw no living Being, but One was in the bush, in the heat of the flames, who knew him and addressed him by name. Who could this be but the Divine Being?
