CAB⁽ⁱ⁾ ³⁰ And forty years having been fulfilled, an Angel of the Lord appeared to him in a flame of fire in a bush, in the wilderness of Mount Sinai. ³¹ And Moses, seeing it, marveled at the sight; and as he approached it to observe closely, the voice of the Lord came to him, ³² saying, 'I am the God of your fathers--the God of Abraham, and the God of Isaac, and the God of Jacob.' And Moses was trembling and was not bold enough not look closely.
