And We have put a seal upon their hearts, so that they hearken not. 100 Unto those [earlier] communities - some of whose stories We [now] relate unto thee - there had indeed come apostles of their own with all evidence of the truth; but they would not believe in anything to which they had once given the lie: thus it is that God seals the hearts of those who deny the truth; 101 Most of them We found not men (true) to their covenant: but most of them We found rebellious and disobedient. 102 After them We sent Moses with Our signs to Pharaoh and his chiefs. But they willfully rejected them. Consider the end of the evil-doers. 103 And Musa said: O Fir'awn! I am an apostle 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 He said: If you have come with a sign, then bring it, if you are of the truthful ones. 106 So Moses threw his staff, and suddenly it was a serpent, manifest. 107 And he drew forth his hand, and lo, it was white to the beholders. 108
