Thus God seals up the hearts of those who deny the truth. 101 We did not find the covenant upheld by the majority of them, but We found most of them evildoers. 102 After those We sent forth Moses with Our signs to Pharaoh and his assembly, but with it they harmed. Look at the end of the corrupters. 103 Moses said: O Pharaoh! Lo! I am a messenger from the Lord of the Worlds, 104 duty-bound to say nothing about God but the truth, and I have brought you a clear sign from your Lord. Let the Children of Israel go with me." 105 [Pharaoh] said, "If you come with a sign, then produce it, if you are telling the truth." 106 So Moses threw down his staff and suddenly it turned into a real serpent. 107 And he drew forth his hand (from his bosom), and lo! it was white for the beholders. 108
