And David said, Is there yet any that is left of the house of Saul, that I may show him kindness for Jonathan's sake?

Saul. David was solicitous only about the descendants of Jonathan, who was the eldest son. The rest he afterwards gave up to be crucified, while he ordered the patrimony of Saul to be given to Miphiboseth, who was now about twenty years old. (Salien, the year before Christ 1058.)
It is rather wonderful that David had not thought of his old friend sooner. But we are not obliged to suppose that he had reigned fifteen years, without being mindful of his repeated promises to Jonathan, 1 Kings xx. 42. (Haydock)
This event took place towards the beginning of his reign. (Calmet)
