And when he was fully grown and in the perfection of his strength, We gave him judgment and knowledge; even so do We recompense the good-doers. 14 And he entered the city at a time of carelessness of its folk, and he found therein two men fighting, one of his own caste, and the other of his enemies; and he who was of his caste asked him for help against him who was of his enemies. So Moses struck him with his fist and killed him. He said: This is of the devil's doing. Lo! he is an enemy, a mere misleader. 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 Said he: "O my Sustainer! [I vow] by all the blessings which Thou hast bestowed on me: Nevermore shall I aid such as are lost in sin!" 17 And morning found him in the city, fearing, vigilant, when behold! he who had appealed to him the day before cried out to him for help. Moses said unto him: Lo! thou art indeed a mere hothead. 18 And when he sought to seize him who was an enemy unto them both, he said: O Musa wouldst thou slay me as thou didst slay a person yesterday? Thou seekest only to be a tyrant in the land, and thou seekest not to be of the reconcilers. 19 A man came running from the far side of the city, and said, "Moses, the authorities are conspiring to kill you, so leave the city. I am one of your well-wishers." 20 He therefore got away therefrom, looking about, in a state of fear. He prayed "O my Lord! save me from people given to wrong-doing." 21
