The garment of Saul
"The Lord forbid that I should do this thing unto my master," he said "to stretch forth my hand against him, seeing he is the anointed of the Lord," and in this way he kept his servants from harming Saul, and after Saul awoke he went out of the cave.
David also went out of the cave and cried,
"My Lord the King!"
And when Saul turned David bowed down to him and asked him why he listened to men who said that he wished to harm the king, and then he told him how the Lord had given him into his hand in the cave, but he would not touch the Lord's anointed to harm him.
"See, my father," he cried "see the skirt of thy robe in my hand. I have not sinned against thee, yet thou huntest my soul to take it."
Much more he said, and asked the Lord to judge between them, and Saul's hard heart was moved so that he wept aloud.
"Is this thy voice, my son David," he said, "Thou art more righteous than I, for thou hast rewarded me good, whereas I have rewarded thee evil," and he made a covenant with David. For though he made no promise to spare David's life, he made David promise to spare the life of his children when he should be made king.
But a year was hardly past before the evil spirit was again upon Saul, and he went out with three thousand men to hunt for David. Saul's camp was on a hill, and David saw where it was. At night he took Abishai, one of his warriors, and went down from the cliffs to Saul's camp, where Saul lay sleeping in a trench, and the spear stuck in the ground by his pillow, while all his men lay around him. Abishai wished to strike him through with the spear, but David said,
"Destroy him not, for who can stretch forth his hand against the Lord's anointed and be guiltless? The Lord shall smite him, or his day shall come to die, or he shall fall in battle and perish; but take thou now the spear that is at his pillow, and the cruse of water, and let us go."
