ASV⁽ⁱ⁾ ³⁰ And when forty years were fulfilled, an angel appeared to him in the wilderness of Mount Sinai, in a flame of fire in a bush. ³¹ And when Moses saw it, he wondered at the sight: and as he drew near to behold, there came a voice of the Lord, ³² I am the God of thy fathers, the God of Abraham, and of Isaac, and of Jacob. And Moses trembled, and durst not behold. ³³ And the Lord said unto him, Loose the shoes from thy feet: for the place whereon thou standest is holy ground.
