Wherefore David arose and went, he and his men, and slew of the Philistines two hundred men; and David brought their foreskins, and they gave them in full tale to the king, that he might be the king’s son in law. And Saul gave him Michal his daughter to wife.
Saul feared David because he sensed that God had left him and was with David instead. Note this well: those truly great and to be reverenced have God with them. David's wise behavior only deepened Saul's fear, for wisdom commands respect where threats and hectoring earn only the contempt of the discerning. Saul foolishly removed him from court, thinking to weaken him, but gave David instead a chance to win the people's love.
