King Saul was jealous of David, but Saul offered his daughter, Michal to David as a wife. David said he was too poor to give a dowry to Saul for his daughter, but Saul said he wanted no dowry, but wanted David to avenge him (Saul) upon the Philistines by bringing 100 foreskins of the enemy back to him. But Saul's motive was not what he said, but rather he wanted David to engage in battle with the Philistines in hopes that David would be killed.
David was King in Hebron for several years until the death of Saul. During that time, Saul pursued him intermittently, believing that David threatened his (Saul's) monarchy. At one point, David had to hole up in the territory of the Philistine King Achish. When Achish's men wanted to kill David, he pretended to be insane and they let him be.
The evolution of Saul's attitude toward David ... as so clearly interpreted in the book on the subject by Rabbi Dr. David Novak ... is the gripping picture of the descent of a tormented soul into his own internal paranoid hell. At one point Saul was simply wary of David, because he imagined that David would try to take the throne away from his son, Jonathan. And then, seemingly the next day, Saul was ready to kill his son, because of Jonathan's friendship with David. No, the thought of David taking over the reign as king of Israel drove Saul to insanity.
God protected David from Saul's attempts to harm him, providing him with wisdom to navigate dangerous situations and securing his safety. God also reassured David of his presence and faithfulness, giving him the strength to endure the challenges he faced.
Traditional chronology states that David was fleeing from Saul for about one-and-one-half years. See also:More about King DavidWhy didn't David kill Saul?
Saul was jealous of David to the degree it became a blind rage. In 1 Sam 18:7 people danced singing "Saul has killed his thousands, and David his ten thousands". This infuriated Saul who wanted to kill David. Saul was also afraid of David because the Lord was with David and not him (1 Sam 18:12).
No it is not so, king saul tried to kill David.
Jonathan helped David by warning him of King Saul's intentions to kill him, providing him with resources and support to escape, and advocating on his behalf to try to reconcile David with King Saul. Jonathan also affirmed his friendship and loyalty to David, despite the circumstances.
Saul seemed to realize that God had chosen David as his replacement, but contrary to Saul's belief David never planned any sort of rebellion, only fleeing from Saul when he attacked. In fact, on two occasions David had a chance to kill Saul (once when he was sleeping, once when they were in a dark cave where Saul could not see him) but refused, claiming that Saul was still God's anointed and thus inviolable. When Saul was killed by an Amalekite David had the perpetrator killed.
