191 Saul now urged his servants and his son Jonathan to assassinate David. But Jonathan, because of his strong affection for David, 2 told him what his father was planning. "Tomorrow morning," he warned him, "you must find a hiding place out in the fields. 3 I'll ask my father to go out there with me, and I'll talk to him about you. Then I'll tell you everything I can find out." 4 The next morning Jonathan spoke with his father about David, saying many good things about him. "The king must not sin against his servant David," Jonathan said. "He's never done anything to harm you. He has always helped you in any way he could. 5 Have you forgotten about the time he risked his life to kill the Philistine giant and how the Lord brought a great victory to all Israel as a result? You were certainly happy about it then. Why should you murder an innocent man like David? There is no reason for it at all!" 6 So Saul listened to Jonathan and vowed, "As surely as the Lord lives, David will not be killed." 7 Afterward Jonathan called David and told him what had happened. Then he brought David to Saul, and David served in the court as before.

(Read 1 Samuel 19:1-10)
How forcible are right words! Saul was, for a time, convinced of the unreasonableness of his enmity to David; but he continued his malice against David. So incurable is the hatred of the seed of the serpent against that of the woman; so deceitful and desperately wicked is the heart of man without the grace of God, Jeremiah 17:9.
