KJ2000⁽ⁱ⁾ ³⁰ And when forty years were expired, there appeared to him in the wilderness of mount Sinai an angel of the Lord in a flame of fire in a bush. ³¹ When Moses saw it, he wondered at the sight: and as he drew near to behold it, the voice of the Lord came unto him, ³² Saying, I am the God of your fathers, the God of Abraham, and the God of Isaac, and the God of Jacob. Then Moses trembled, and dared not behold. ³³ Then said the Lord to him, Put off your shoes from your feet: for the place where you stand is holy ground.
