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 He entered the city unnoticed by its people, and there he encountered two men fighting with one another -- one of his own people and the other one of his enemies. The one who belonged to his own people cried out to him for help against his foe -- whereupon Moses struck him down with his fist, thereby causing his death. Moses said, "This is Satan's doing; he is an open foe, leading man astray." 15 He said, "My Lord, indeed I have wronged myself, so forgive me," and He forgave him. Indeed, He is the Forgiving, the Merciful. 16 He said, "My Lord, because of the favour that You have shown me, I vow that I will never be a helper of the guilty." 17 In the morning he came to the city, fearful and hesitant. Just then he who had asked him for help the day before called out for help (again). "You are indeed a meddlesome fellow," Moses said to him. 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 Then a man came running from the furthest part of the city, 'Moses' he said, 'the Assembly are plotting to kill you. Leave, for I am one of your sincere advisers' 20 So he departed therefrom, fearful and vigilant; he said, 'My Lord, deliver me from the people of the evildoers.' 21
