“And it came about that, as I made my journey, and drew near to Damascus, about noon, suddenly there shone from heaven a great light round about me.”
He described how, as he was making the journey to Damascus around noon, a great light from heaven had shone around him, the light of the Shekinah, the light of God, and yet here as revealed in Jesus Christ. The reference to ‘noon' (mesembrian) might have been intended to remind the knowledgeable among his hearers of Moses' words in Deuteronomy 28:28-29, ‘The Lord will smite you --- with blindness and with astonishment of heart, and you will grope at noonday (mesembrian) ---.' The point was thus that he had been smitten, and blinded and filled with astonishment because he had disobeyed the Lord.
