Exodus 3:3-5

New Revised Standard Version, Anglicised Catholic Edition

³ Then Moses said, ‘I must turn aside and look at this great sight, and see why the bush is not burned up.’ ⁴ When the Lord saw that he had turned aside to see, God called to him out of the bush, ‘Moses, Moses!’ And he said, ‘Here I am.’ ⁵ Then he said, ‘Come no closer! Remove the sandals from your feet, for the place on which you are standing is holy ground.’
