I want an interpretation of... "and He increased him abundantly in knowledge and physique."

"Bastah" means an increase, merit, and spaciousness. Allah increased Talut in knowledge, so he became the most knowledgeable among the Children of Israel in religious law and the arts of war. He also increased him in physical stature, making him great and robust. The qualification for leadership is achieved through knowledge and strength, so a leader must be the most knowledgeable and strongest among his people.
