1. Samuel 20:12

In the field, where they were both entirely free from observation, Jonathan first of all renewed his covenant with David, by vowing to him on oath that he would give him information of his father's feelings towards him (Sa1 20:12, Sa1 20:13); and then entreated him, with a certain presentiment that David would one day be king, even then to maintain his love towards him and his family for ever (Sa1 20:14-16); and lastly, he made David swear again concerning his love (Sa1 20:17), and then gave him the sign by which he would communicate the promised information (Sa1 20:18-23). Sa1 20:12-15 Sa1 20:12 and Sa1 20:13 are connected. Jonathan commences with a solemn invocation of God: "Jehovah, God of Israel!" and thus introduces his oath. We have neither to supply "Jehovah is witness," nor "as truly as Jehovah liveth," as some have suggested. "When I inquire of my father about this time to-morrow, the day after to-morrow (a concise mode of saying 'to-morrow or the day after'), and behold it is (stands) well for David, and then I do not send to thee and make it known to thee, Jehovah shall do so to Jonathan," etc. ("The Lord do so," etc., the ordinary formula used in an oath: see Sa1 14:44). The other case is then added without an adversative particle: "If it should please my father evil against thee (lit. as regards evil), "I will make it known to thee, and let thee go, that thou mayest go in peace; and Jehovah be with thee, as He has been with my father." In this wish there is expressed the presentiment that David would one day occupy that place in Israel which Saul occupied then, i.e., the throne. - In Sa1 20:14 and Sa1 20:15 the Masoretic text gives no appropriate meaning.

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).
