And when he attained his full strength and was [mentally] mature, We bestowed upon him judgement and knowledge. And thus do We reward the doers of good. 14 And he entered the city unnoticed by the people and found two men fighting, one was of his own party, and the other of his enemies. The one of his party appealed for his help against his enemy, Moses struck and killed him, and said: 'This is the work of satan, he is surely a clear, misleading enemy. 15 "O Lord," he prayed, "I have done wrong, forgive me." And God forgave him. Verily He is forgiving and kind. 16 He said: "O my Lord! For that Thou hast bestowed Thy Grace on me, never shall I be a help to those who sin!" 17 He remained in the city but very afraid and cautious. Suddenly the person who asked him for help the previous day asked him for help again. Moses said, "You are certainly a mischievous person". 18 But then as soon as he was about to lay violent hands on the man who was their [common] enemy, the latter exclaimed: "O Moses, dost thou intend to slay me as thou didst slay another man yesterday? Thy sole aim is to become a tyrant in this land, for thou dost not care to be of those who would set things to rights!" 19 There came a man running from the other part of the city. "O Moses," he said, "the chiefs are deliberating to kill you. Go away from the city. I wish you well." 20 So he departed therefrom, fearful and vigilant; he said, 'My Lord, deliver me from the people of the evildoers.' 21
