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:

Jonathan spake good of David. He told his father he was committing a great sin to plot against the life of a man who had rendered the most invaluable services to his country, and whose loyalty had been uniformly steady and devoted. The strong remonstrances of Jonathan produced an effect on the impulsive mind of his father. Since he was still susceptible of good and honest impressions, he bound himself by an oath to relinquish his hostile purpose, and thus, through the intervention of the noble-minded prince, a temporary reconciliation was effected, in consequence of which David was again employed in the public service.
