Thus God seals up the hearts of those who deny the truth. 101 We did not find many of them faithful to their promises, and found many of them disobedient. 102 So We sent Moses with miracles after (these apostles) to the Pharaoh and his nobles, but they behaved with them high-handedly. See then the end of the authors of evil. 103 Moses said: "O Pharaoh, I have been sent by the Lord of all the worlds; 104 incumbent upon me is that I say nothing of Allah except the truth. I bring you a clear proof from your Lord. So let the Children of Israel depart with me' 105 Said he, 'If thou hast brought a sign, produce it, if thou speakest truly.' 106 So Moses threw his staff, and suddenly it was a serpent, manifest. 107 Then he uncovered his hand and it appeared sheer white to the onlookers. 108
