John Gill's Bible Commentary Ver. 5. And David said unto the young man that told him , etc.] These tidings: how knowest thou that Saul and Jonathan his son be dead ? this he particularly inquired after, as what most affected him, and was most material for him to know; and his meaning is, whether he had this of his own sight and knowledge, or by report.
Matthew Henry Commentary
Verses 1-10 - The blow which opened David's way to the throne was given about the time he had been sorely distressed. Those who commit their concerns to the Lord, will quietly abide his will. It shows that he desired no Saul's death, and he was not impatient to come to the throne.
