18:4 Yehonatan took off the cloak and tunic he was wearing and gave them to David
The Sages view the mutual affection shared by Yehonatanand David as the epitome of true love between friends, as neither has any ulterior motives (Ethics of the Fathers 5:16). Indeed, as the heir apparent, Yehonatanhas every reason to be jealous of David who was destined to be the new king of Israel. But instead, Yehonatanaccepts the decree. He not only protects David from his father, King Shaul, but also gives him the symbol of his position as heir to the throne. Yehonatanrecognizes that David is to be the founder of the eternal dynasty of Israel.Comment
5David went out [with the troops], and he was successful in every mission on which Shaul sent him, and Shaul put him in command of all the soldiers; this pleased all the troops and Shaul‘s courtiers as well.
6 When the [troops] came home [and] David returned from killing the Philistine, the women of all the towns of Yisrael came out singing and dancing to greet King Shaul with timbrels, shouting, and sistrums.
17Shaul said to David, “Here is my older daughter, Merab; I will give her to you in marriage; in return, you be my warrior and fight the battles of Hashem.” Shaul thought: “Let not my hand strike him; let the hand of the Philistines strike him.”
21Shaul thought: “I will give her to him, and she can serve as a snare for him, so that the Philistines may kill him.” So Shaul said to David, “You can become my son-in-law even now through the second one.”
25 And Shaul said, “Say this to David: ‘The king desires no other bride-price than the foreskins of a hundred Philistines, as vengeance on the king’s enemies.’”—Shaul intended to bring about David‘s death at the hands of the Philistines.—
27David went out with his men and killed two hundred Philistines; David brought their foreskins and they were counted out for the king, that he might become the king’s son-in-law. Shaul then gave him his daughter Michal in marriage.
