Indeed I have come unto you from your Lord with a clear proof. So let the Children of Israel depart along with me." 105 He said: "If you have brought a sign then display it, if what you say is true." 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
