3 Ref And Moses said, I will go and see this strange thing, why the tree is not burned up,
4 Ref And when the Lord saw him turning to one side to see, God said his name out of the tree, crying, Moses, Moses. And he said, Here am I.
5 Ref And he said, Do not come near: take off your shoes from your feet, for the place where you are is holy.
