Acts 13:11

“And now, behold, the hand of the Lord is on you, and you will be blind, not seeing the sun for a season.” And immediately there fell on him a mist and a darkness, and he went about seeking some to lead him by the hand.'

‘The hand of the Lord is on you.' This is a typical Old Testament phrase (compare Joshua 4:24; 1 Samuel 12:15; Psalms 75:8) which would be meaningful to someone who claimed connection with Old Testament prophets (he was a false prophet), and would be a reminder not to make such claims before God. As a self-proclaimed prophet he himself should have been able to call for ‘the hand of the Lord' to act. The fact that His hand was against him should have given him pause to think.

The temporary blindness put on him by God (as He had previously put it on Saul) was symbolic of his spiritual blindness. If we knew all the circumstances we might more fully understand why it was bestowed on him. He may well have challenged Saul and threatened him with his sorcery, or himself have aimed a curse, never dreaming that it would be returned. So the blindness may well have been connected with things that he had said and spells that he had attempted to use. Now his vulnerability was revealed to all by his being led about by the hand. He who had claimed to lead others, now had to be led.
