14 Preface وَلَمّا بَلَغَ أَشُدَّهُ وَاستَوىٰ آتَيناهُ حُكمًا وَعِلمًا ۚ وَكَذٰلِكَ نَجزِي المُحسِنينَYusuf AliWhen he reached full age, and was firmly established1 (in life), We bestowed on him wisdom and knowledge: for thus do We reward those who do good.Full age may be taken to be mature youth, say between 18 and 30 years of age. By that time a person is fully established in life: his physical build is completed, and his mental and moral habits are formed. In this case, as Moses was good at heart, true and loyal to his people, and obedient andjust to those among whom he lived, he was granted wisdom and knowledge from on high, to be used for the times of conflict which were coming for him. His internal development being complete, he now goes out into the outer world, where he is again tried and proved, until he gets his divine commission.
