Now, see the nature of the consequence for the corrupters! 103 Moses said: 'Pharaoh, 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 Then he drew out his hand, and it appeared luminous to all beholders. 108
