1. Samuel 20:13

The Lord be with thee, as he hath been with my father - From this, and other passages here it is evident that Jonathan knew that the Lord had appointed David to the kingdom.

DAVID CONSULTS WITH JONATHAN FOR HIS SAFETY. (Sa1 20:1-10) David fled from Naioth in Ramah, and came and said before Jonathan--He could not remain in Naioth, for he had strong reason to fear that when the religious fit, if we may so call it, was over, Saul would relapse into his usual fell and sanguinary temper. It may be thought that David acted imprudently in directing his flight to Gibeah. But he was evidently prompted to go thither by the most generous feelings--to inform his friend of what had recently occurred, and to obtain that friend's sanction to the course he was compelled to adopt. Jonathan could not be persuaded there was any real danger after the oath his father had taken; at all events, he felt assured his father would do nothing without telling him. Filial attachment naturally blinded the prince to defects in the parental character and made him reluctant to believe his father capable of such atrocity. David repeated his unshaken convictions of Saul's murderous purpose, but in terms delicately chosen (Sa1 20:3), not to wound the filial feelings of his friend; while Jonathan, clinging, it would seem, to a hope that the extraordinary scene enacted at Naioth might have wrought a sanctified improvement on Saul's temper and feelings, undertook to inform David of the result of his observations at home.

The Lord do so and much more to Jonathan,.... Recompense evil more than can be thought of and expressed, should he neglect to inform David of the good disposition of Saul unto him: but if it please my father to do thee evil; if he seems determined upon it to take away thy life: then I will show it thee; not by a messenger, by whom it would not be safe to communicate it, lest by that means Saul would know where he was, and come and slay him; but Jonathan would come himself, and acquaint him with it: and send thee away, that thou mayest go in peace; give him leave, and advise him to depart, and provide for his own safety, adding his blessing on him, and prayer for him: and the Lord be with thee, as he hath been with my father; in the beginning of his reign, giving him counsel and advice in all things, and victory over his enemies, succeeding and prospering him in whatsoever he engaged in; the Targum is,"the Word of the Lord be for thy help, &c.'' Jonathan seemed to be fully apprized that David was to succeed in the kingdom.

David, having several times narrowly escaped Saul's fury, begins to consider at last whether it may not be necessary for him to retire into the country and to take up arms in his own defence. But he will not do so daring a thing without consulting his faithful friend Jonathan; how he did this, and what passed between them, we have an account in this chapter, where we have as surprising instances of supernatural love as we had in the chapter before of unnatural hatred. I. David complains to Jonathan of his present distress, and engages him to be his friend (Sa1 20:1-8). II. Jonathan faithfully promises to get and give him intelligence how his father stood affected to him, and renews the covenant of friendship with him (Sa1 20:9-23). III. Jonathan, upon trial, finds, to his grief, that his father was implacably enraged against David (Sa1 20:24-34). IV. He gives David notice of this, according to the appointment between them (Sa1 20:35-42).

20:13 may the Lord strike me: Jonathan invoked a curse upon himself to reassure David that he would keep his promise. • as he used to be with my father: Jonathan recognized that David had received the blessing from God that his father had once had. The divine favor that had brought Saul into royal office (9:14–10:1) would bring David into royal office as Saul’s replacement. Jonathan accepted this even though he was the natural successor to Saul.
