1 Samuel 18:8

What can he have more? No time interval is given between the announcement of God’s choice of another man, “better than thou” (ch. 15:28), as king, and this present experience of David in the court of the king. Though it is probable that several years had passed, Saul would certainly be on the watch for signs of the man who was to succeed him (see v. 9). He had recently proved powerless before the Philistines, and had it not been for the courageous exploit of this shepherd lad he might have lost his own life. Yet, he resented the thought that this lad whom he had honored and associated closely with himself might be winning away from him the affections of the people and the army as well. What kind of gratitude would that be? Time had not eased the smart of the prophetic rebuke (see ch. 15:23). Saul again gave way to feelings of discontent and evil surmisings until his jealous mind finally became deranged.
