1 Samuel 20:13
The LORD do so and much more to Jonathan: but if it please my father to do thee evil, then I will shew it thee, and send thee away, that thou mayest go in peace: and the LORD be with thee, as he hath been with my father.
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.
