And when he reached his full strength and was ripe, We gave him wisdom and knowledge. Thus do We reward the good. 14 He came to the city when the people were in a care-free mood, and saw two men quarrelling, one belonging to his community, the other to his enemies. The man who belonged to his community appealed for help against the one who belonged to the enemies. Moses struck him a blow with his fist and finished him off. "This is of Satan's doing," he said. "He is certainly an enemy and a corrupter." 15 He said: My Lord! surely I have done harm to myself, so do Thou protect me. So He protected him; surely He is the Forgiving, the Merciful. 16 He said: My Lord! because Thou hast bestowed a favor on me, I shall never be a backer of the guilty. 17 And he became inside the city fearful and anticipating [exposure], when suddenly the one who sought his help the previous day cried out to him [once again]. Moses said to him, "Indeed, you are an evident, [persistent] deviator." 18 When Moses was about to attack their enemy, he said, "Moses, do you want to kill me as you slew a soul the other day? Do you want to become a tyrant in the land, not a reformer?" 19 Then came a man from the furthest part of the city, running; he said, 'Moses, the Council are conspiring to slay thee. Depart; I am one of thy sincere advisers.' 20 So he went forth from thence, looking fearfully about him, and prayed: "O my Sustainer! Save me from all evildoing folk!" 21
