1 Samuel 19:4
And Jonathan spake good of David unto Saul his father, and said unto him, Let not the king sin against his servant, against David; because he hath not sinned against thee, and because his works have been to thee-ward very good: And Jonathan spake good of David unto Saul his father, and said unto him, Let not the king sin against his servant, against David; because he hath not sinned against thee, and because his works have been to thee-ward very good:
This entreaty belongs to the history of the friendship between Jonathan and David, a bond sealed by a covenant to be united as brothers and shown when Jonathan bestowed on David his own royal robe and weapons. In it Jonathan appeals to his father Saul not to commit sin against his servant David by taking his life. The appeal is grounded on two facts, that David had done Saul no wrong and that his deeds toward Saul had been very good. That goodness of service had preserved the honor of Israel and even its national existence by overcoming the nation's enemies. To put to death the man whom God had employed to deliver Israel would fasten terrible guilt upon Saul.
